Uses two chairs to isolate and drill three core jump-back/jump-through actions: L-sit holds with thigh-to-chest pulses, lift-ups with a strong curl, and crouch-and-spring transitions. Three progressive rounds build the specific strength, timing, and coordination needed for clean vinyasa transitions. The elevated position lets you safely rehearse the mechanics—leaning forward, drawing legs back, landing in balance—without the floor getting in the way. Builds upper body and core strength while teaching your body the actual shape and rhythm of the movement. **Benefit:** Stronger, cleaner jump-backs and jump-throughs; upper body and core strength; confidence in transitions.
