Durability +1 is a strength and endurance workout that upgrades exactly one stat, exactly the way the name promises: incrementally, permanently, through use. Squats, shoulder taps and a single push-up live between six 20-count holds - and the holds are the real armor-smithing. This isn't a workout about doing more. It's a workout about lasting longer, which is a different and rarer attribute.
The circuit runs without rest between exercises and is built as two matched wings. The first is for the legs: a 20-count squat hold, 20 squats, and another 20-count hold, so the muscles work statically, then dynamically, then statically again on accumulated fatigue. The second wing mirrors the pattern up top: a 20-count plank hold, 20 shoulder taps, another 20-count hold. Bookending movement with isometrics is what durability training actually looks like - joints, tendons and stabilizers adapt to time under tension, not just to reps. Then comes the final line: 1+ push-up. One is the requirement. The plus is the upgrade path - every clean rep you add on arms that have just held for 40 counts is another point quietly banked.
Hold the squat position at parallel with weight in your heels and arms extended - no creeping upward as the count grinds on. Keep squats full-depth and unhurried. In the plank holds, stack hands under shoulders and hold one line from head to heels. During shoulder taps, set your feet slightly wider and keep hips motionless as each hand lifts. Make the push-up - and every bonus rep - full range.
+1 doesn't sound like much until you realize it never resets. Stack enough of them and you become very hard to break.
Make it Harder: Turn 1+ into 5+ and extend every hold to a 30-count.
Make it Easier: Halve all holds to a 10-count and take the push-up from your knees.
