Three timers run as one continuous session here: a mobility warm-up of arm circles, hip openers, and leg swings; eight rounds of 30 seconds work and 30 seconds rest in the middle; and a cooldown of three one-minute stretches — hamstring stretch, pigeon pose, and child’s pose. A 30-second transition separates each block, and the full sequence takes 13:15.
The parts people skip are exactly the ones this structure protects. Because the warm-up rolls straight into the work block and the stretches begin before you can wander off, prep and recovery happen by default rather than by discipline. To make the frame yours, open the preset in the editor — substitute your own mobility drills, change the work-to-rest ratio, or extend the stretches.
A four-station strength circuit followed by a short HIIT finisher. Build the work, then burn it out — a complete gym-day stack in under twenty minutes.
Bike intervals straight into run intervals — the classic triathlete brick. Two HIIT blocks chained back-to-back to train the transition under fatigue.
