This is the equipment version of the Hypertrophy Abs Challenge. Same logic, same three-day cycle, same slow count - but performed on a bench, which changes everything about how hard each rep is. If you have access to a bench, this is the version to do. If you do not, the no-equipment version delivers the same result on the floor.

Here is why the bench matters. On the floor, a leg raise stops when your heels reach the ground and a sit-up only loads the top half of the movement. On a bench, your legs can travel below the level of your body, and a decline sit-up keeps your abs working through the entire range instead of handing the bottom half to gravity. More range means more work per rep. That is why the reps here are lower than the floor version - 8 building to 10, rather than 10 building to 12. Fewer reps, considerably more work in each one.

Over 30 days the reps go up by two. The work your abs do roughly doubles. That gap is the whole point: visible abs need muscle size, muscle size comes from overload, and overload here is delivered through range of motion, slow counts, pauses and a hold rather than through piling on reps.

Equipment: A flat or adjustable exercise bench is all you need. If you have an adjustable bench, set a mild decline for the sit-ups - the steeper the decline, the harder the movement, so start shallow. A flat bench works perfectly well for the entire challenge.

Optional additions: A dumbbell, weight plate or kettlebell held against your chest during sit-ups is the simplest way to add load if the reps stop being hard - start light, around 2 to 5kg. Ankle weights add load to the leg raises the same way. A loaded backpack or a heavy book works just as well as a plate if you are training at home. None of this is required, and you should only add weight once you can complete every set at the prescribed count with clean form.

The structure: The challenge runs on a repeating three-day cycle - one hard day, two easy days. The hard days (1, 4, 7, 10, 13, 16, 19, 22, 25, 28 and 30) are where the muscle is built. The days in between are active rest: two quick sets at normal speed, no burn, just enough to keep the muscles switched on. There are no true rest days, but two thirds of this calendar is deliberately light. That is not padding. Muscle is built between hard sessions, not during them, and if you turn the easy days into hard ones you will arrive at day 30 too fatigued to do the work that matters.

How to do a bench leg raise: Lie flat on your back along the bench with your legs extended past the end of it. Reach back and grip the edges of the bench beside or behind your head - this anchors your upper body and lets you work without sliding. Lower your legs, keeping them straight and together, until they drop below the level of the bench. Then raise them until they are roughly vertical. That is one rep. Your legs never rest on the bench between reps. Keep your lower back in contact with the bench throughout: if it arches away, you have lowered too far, so shorten the range.

How to do a decline sit-up: Hook your feet under the roller pads or the end of the bench so you are secure. Cross your arms over your chest. Lower yourself back with control until your torso is roughly in line with the bench, then curl up until you are upright. That is one rep. Keep your chin off your chest and your neck relaxed. Do not pull yourself up with momentum or let yourself drop back - the lowering half is where most of the work happens, so control it.

How to do a leg hold: This is the same position as the bench leg raise. After your last rep, stop with your legs level with the bench or just below it and hold, legs straight, lower back in contact with the bench, for the full count. The lower your legs, the harder it gets. The hold comes straight off your last leg raise with no rest and no putting your legs down in between.

Normal count: This applies to every active rest day and to days 1 through 7. Bench leg raises: 2 counts up, 3 counts down. Decline sit-ups: 1 count up, 3 counts down. Controlled, but not laboured.

Slow count: This starts on day 10 and applies to every hard day from then on - days 10, 13, 16, 19, 22, 25, 28 and 30.

• Bench leg raises: 2-counts up, 1-count hold at the top, 4-counts down, 1-count hold at the bottom before the next rep.
• Decline sit-ups: 1-count up, 1-count squeeze at the top, 4-counts down.

The slow count is the single most important instruction in the challenge. A slow-count rep takes almost twice as long as a normal one and does close to twice the work. If you speed up, the challenge stops working.

Rest: 90 seconds between sets on hard days, 60 seconds on active rest days, and 90 seconds between the two exercises on hard days. Complete all sets of the leg raises first, then move to the sit-ups. The long rests are deliberate. This is strength work, not a conditioning circuit - you need to recover enough to make the next set genuinely hard. Rushing the rest turns a hypertrophy session into a burner and defeats the purpose.

What to expect: Week one will feel manageable but the range of motion will already tell you this is different from floor work. Day 10 is where the challenge actually starts, and the slow count will surprise you: the same eight reps you cruised through on day 7 will burn. Week three adds the hold, and the hold is where most people discover what a fatigued ab muscle feels like, because your legs are already tired from ten slow raises before it begins. Week four is the peak. If you have done the work, day 30 will feel hard but achievable - and it should be your best session of the month, not your worst.

If you feel nothing at all: If you are new to ab training and the burn everyone talks about is not happening, you are not doing anything wrong. Your body has not yet learned to recruit these muscles properly, and stronger neighbours - especially your hip flexors - quietly take over the work. If you feel leg raises in the front of your hips instead of your midsection, that is what is happening. Slow down further, press your lower back into the bench, and shorten the range. For most people the burn shows up within 4 to 8 weeks of consistent training. Keep going.

Make it easier: Bend your knees to 90 degrees on the leg raises - this shortens the lever and dramatically reduces the load while training exactly the same muscles. Shorten the range so your legs stop level with the bench rather than dropping below it. Flatten the bench for the sit-ups instead of using a decline. Shorten the holds to whatever you can manage with your back flat. Drop one set rather than skipping a day. On active rest days, one set instead of two is fine if you are still sore.

Make it harder: Hold a weight against your chest during the sit-ups, or between your feet during the leg raises. Increase the decline angle on the bench. Extend your arms overhead on sit-ups instead of crossing them on your chest. Add a 2-count hold at the bottom of every leg raise instead of 1. Hold your legs lower during the holds. Do not add reps: the whole point of this challenge is that progress comes from making the same reps harder.

Optional SUBQUEST

SUBQUEST Day 1: before your first set, do one all-out set of bench leg raises and one all-out set of decline sit-ups with clean form. Stop the moment your lower back lifts off the bench or your speed collapses. Write both numbers down.

SUBQUEST Day 30: after you finish your last set, repeat the same test under the same rules and at the same bench angle. Compare the numbers. This is your proof, and it is more honest than a mirror at this stage - visible change takes around three months, but strength change shows up in one.

Day by Day

Day 1: 8 bench leg raises x 3 sets, 8 decline sit-ups x 3 sets, 90 seconds rest between sets and exercises. Normal count. Your baseline session. Do 8 bench leg raises at 2 counts up and 3 counts down, rest 90 seconds, repeat for 3 sets. Rest 90 seconds, then do 8 decline sit-ups at 1 count up and 3 counts down for 3 sets with the same 90 second rest. Focus entirely on form and on finding your range today: lower your legs only as far as you can go with your back still touching the bench. If you are doing a SUBQUEST, do your two max sets before you start.

Day 2: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest. Normal count, easy pace. Two sets of each with 60 seconds between them. This should take about two minutes and should not burn at all. If it burns, you are going too hard.

Day 3: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest again, same as yesterday. You may feel some soreness from day 1 - gentle movement usually helps soreness rather than making it worse, so do the work and keep it light.

Day 4: 8 bench leg raises x 3 sets, 8 decline sit-ups x 3 sets, 90 seconds rest between sets and exercises. Hard day, identical to day 1. Normal count still. The repeat is deliberate - you are grooving the pattern and settling into your bench setup before the load increases. Take the full 90 seconds between sets and the 90 seconds between exercises.

Day 5: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest. Easy pace, no pauses, no burn.

Day 6: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest. Same again. Two minutes of work, that is all.

Day 7: 8 bench leg raises x 4 sets, 8 decline sit-ups x 4 sets, 90 seconds rest between sets and exercises. Hard day, first real increase: a fourth set. Still normal count. Same reps, one more round of them. If the fourth set feels significantly harder than the third, that is exactly right.

Day 8: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 9: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest. Rest up - tomorrow is where the challenge changes.

Day 10: 8 bench leg raises x 4 sets, 8 decline sit-ups x 4 sets, 90 seconds rest between sets and exercises. SLOW COUNT. The reps stay at 8, but the count changes and everything gets harder. Bench leg raises: 2 counts up, 1 count hold at the top, 4 counts down, 1 count hold at the bottom. Decline sit-ups: 1 count up, 1 count squeeze, 4 counts down. Expect this to burn in a way nothing before it has. Do not speed up to finish the set - if you cannot maintain the count, stop the set there.

Day 11: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest, back to normal count. You will probably be sore. Keep it light and move through it.

Day 12: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest. Normal count, easy pace.

Day 13: 8 bench leg raises x 4 sets, 8 decline sit-ups x 4 sets, 90 seconds rest between sets and exercises. SLOW COUNT. Identical to day 10. Nothing new added - this is a consolidation day that lets your body adapt to the slow count before the reps go up. It should feel marginally more manageable than day 10 did.

Day 14: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 15: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 16: 10 bench leg raises x 4 sets, 10 decline sit-ups x 4 sets, 90 seconds rest between sets and exercises. SLOW COUNT. Hard day with the rep increase: 10 instead of 8, slow count maintained. This is the only rep jump in the entire challenge and it is worth noting how small it is. Two extra reps at slow count adds roughly 12 to 16 seconds of tension per set.

Day 17: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 18: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 19: 10 bench leg raises + 15-count leg hold x 4 sets, 10 decline sit-ups x 4 sets, 90 seconds rest between sets and exercises. SLOW COUNT. The hold arrives. Do your 10 slow-count bench leg raises, and instead of finishing the set there, stop with your legs level with the bench or just below it and hold for 15 counts. No rest between the last rep and the hold. Then rest 90 seconds and repeat. After 4 sets, rest 90 seconds and do your 10 slow-count decline sit-ups for 4 sets. The hold will feel far longer than 15 counts because your abs are already fatigued - that is the entire point.

Day 20: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest. No holds on active rest days.

Day 21: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 22: 10 bench leg raises + 15-count leg hold x 4 sets, 10 decline sit-ups x 4 sets, 90 seconds rest between sets and exercises. SLOW COUNT. Identical to day 19. Another consolidation day. Focus on keeping your legs low during the hold rather than letting them drift up - as you fatigue, legs creep higher and the exercise gets easier without you noticing.

Day 23: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 24: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 25: 10 bench leg raises + 15-count leg hold x 5 sets, 10 decline sit-ups x 5 sets, 90 seconds rest between sets and exercises. SLOW COUNT. Hard day with a fifth set added. Everything else stays the same. Five sets of raises plus holds, then five sets of sit-ups. This is a long session - budget around 30 minutes including all the rest.

Day 26: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 27: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest.

Day 28: 10 bench leg raises + 20-count leg hold x 5 sets, 10 decline sit-ups x 5 sets, 90 seconds rest between sets and exercises. SLOW COUNT. Peak session. The hold extends to 20 counts. Everything else is as day 25. This is the hardest day of the challenge so far and it should feel like it. Take every second of the rest you are given.

Day 29: 6 bench leg raises x 2 sets, 6 decline sit-ups x 2 sets, 60 seconds rest between sets and exercises. Active rest. Keep it genuinely light - tomorrow is the finish.

Day 30: 10 bench leg raises + 20-count leg hold x 5 sets, 10 decline sit-ups x 5 sets, 90 seconds rest between sets and exercises. SLOW COUNT. The final session, identical to day 28. You are finishing on your hardest workout rather than winding down, and if the month has done its job this will feel like a session you can complete rather than survive. Compare it to day 1: the reps went up by two, and the work you are doing has roughly doubled. If you are doing a SUBQUEST, run your two max sets after you finish.
