This three-round plank circuit tests your strength and your focus with one-minute holds followed by 30 seconds of rest. You’ll work a classic long, strong plank shape—head, torso, pelvis, and legs in one solid column—then add a mountain-climber-style variation: point one foot back like a Shalabhasana leg, then draw the thigh powerfully to the chest before returning to plank. Options include elevating the hands, resting as needed, and choosing your breath (ujjayi or “crow’s beak” lip breathing) so you can scale the challenge to your level while training arm and leg strength, core stability, and a steady, meditative mind under pressure. **This drill develops:** Plank, Chaturanga Dandasana, and the arm, core, and mental stamina needed for strong vinyasas and sustained practice.
