Chase is exactly what the name suggests: a relentless, forward-driving cardio workout that never fully lets the legs rest. High knees and butt kicks run as the backbone of every triplet - 20 reps each, accumulating 60 reps of each across the full set - while hop heel clicks, side-to-side hops, and toe tap hops close each row with a short burst of reactive lower-body work that demands speed, coordination, and a split-second of being entirely airborne.

The high knee and butt kick pairing is a front-to-back hip mobilization cycle: high knees drive the hip flexors and anterior chain; butt kicks recruit the hamstrings and challenge knee flexion speed under load. Together they cover the full running stride, which makes Chase as close to a sprint drill as a stationary workout gets. The finisher exercises at the end of each triplet escalate in coordination demand: heel clicks require a tight midair position with feet together; side-to-side hops add lateral direction change; toe tap hops require the hands to meet the rising knees in the air, demanding hip flexion timing and upper-lower body synchronization simultaneously.

Keep arm drive active throughout the high knees and butt kicks - the arms are not decorative at this pace, they regulate cadence and contribute to cardiovascular output. On toe tap hops, the tap should be genuine contact, not a near-miss; that moment of midair coordination is the point.

Something is gaining on you. Keep moving.

Make it harder: Perform all high knees and butt kicks at sprint pace with maximum arm drive, and add a full jump to every hop variation.

Make it easier: Replace high knees and butt kicks with marching versions - slow, controlled, ground-based - and substitute step heel clicks and lateral steps for the hop finishers.
