Alactic Power Meets Aerobic Base

Alactic Power Meets Aerobic Base

Freestyle sprint repeats target your phosphocreatine system while kickboard kick isolates hip flexor and glute drive — the engine behind turnover speed. Pairing these two recruits fast-twitch fibers without letting compensatory arm mechanics mask weak kick mechanics.

Why Sprint Swimmers Break at the Hips

Why Sprint Swimmers Break at the Hips

Hip-driven propulsion accounts for up to 60% of freestyle velocity, yet most swimmers overtaper their kick under fatigue. Short, fast repeats with controlled rest expose this breakdown point early, training your neuromuscular system to maintain kick amplitude when lactate climbs.

Rest Ratios That Build Race-Sharp Speed

Rest Ratios That Build Race-Sharp Speed

The work-to-rest structure here prioritizes quality over volume — a classic sprint periodization principle where full phosphocreatine replenishment between efforts means each rep is a true speed stimulus, not aerobic grinding. If the repeats feel too easy, shorten rest by 5-second increments before adding distance.
