Rep cycling for size/strength
Strength coach Ironmike recommends cycling movements — e.g., swap barbell squats for hack squats — and varying rep ranges from heavy 5–8 reps to moderate 10–12 reps to keep constant muscle tension without nonstop loading. That practical rep‑range playbook is getting traction as lifters look to maintain progress while reducing injury risk. (x.com)
Coach “Iron Mike” operates a paid coaching site called Coach Iron Mike and posts fitness content under “Iron Mike Biohacking” on TikTok and YouTube ( ). (coachironmike.com) The approach he promoted — swapping movement patterns and deliberately cycling rep bands — maps to a coaching concept labeled “rep‑range cycling” or layered rep‑range programming that explicitly prescribes low (≈3–6), moderate (≈6–12) and high (≈15+) rep bands to bias strength, hypertrophy and endurance adaptations.

(lynleystraining.com) A randomized trial published in PLOS ONE (2019) that compared session‑by‑session randomization of exercises and rep ranges to a fixed program in trained men found similar increases in muscle thickness and strength between groups while the randomized program produced higher intrinsic motivation scores.

(journals.plos.org) Meta‑analyses led by Brad Schoenfeld report that, when total training volume is equated, low‑load (<60% 1RM) and high‑load (≥60% 1RM) resistance training produce comparable hypertrophy, which supports cycling loads and rep ranges instead of continuous maximal loading.
