Back To Business is a cardio and mobility workout for the return you make before you're ready to call it a comeback. Jumping jacks, jack squats, hero squats, bicep extensions and side shoulder taps - a genuinely complete little session wearing the world's most honest disclaimer in its own title. Fully back? No. Moving again, with a plan and a pulse? Absolutely. The "sort of" is doing load-bearing work, and so are you.

The circuit runs without rest between exercises and eases you back into the office in two departments. The first row is the legs' return memo: jumping jacks re-establish bounce and rhythm, jack squats convert that bounce into wide, deep landings, and hero squats fold the whole body from a full overhead reach down into a deep squat and back - the biggest range of motion on the poster, performed ten times, like a formal re-introduction to your own hips. The second row hands the workload to the arms at double volume: 20 bicep extensions and 20 side shoulder taps, light enough to be gentle, long enough to be felt. Nothing here demands yesterday's fitness. Everything here rebuilds the habit that produces tomorrow's.

Keep jumping jacks full and springy with arms reaching overhead. Land jack squats in a genuinely wide stance, hips sinking to parallel before the feet snap back. In hero squats, reach tall, fold deep with control, and grow all the way back up through the fingertips. Keep the arm work deliberate - full extensions, taps landing at the shoulders, no rushing the easy stuff just because it's easy.

Sort of back is still back. The business, it turns out, mostly needed someone to show up - and look who did.

Make it Harder: Double the hero squats to 20 and take the jacks at full pace.

Make it Easier: Step the jumping jacks as half jacks and shallow the squats to a comfortable depth.
