Programming you'd actually want to build.

Strength, hypertrophy, powerlifting, bodybuilding prep. Real loading modes (% 1RM, RPE, RIR), real supersets, real tempo, and a workout player that logs offline because gym wifi is bad.

What's different about Leenen for this niche

RPE-native, not RPE-as-afterthought

Most platforms only do %-based loading. We let you prescribe in RPE/RIR and the client app calculates load on the fly from their previous best.

Per-muscle volume that you can trust

Every exercise has weighted muscle contributions. Total weekly sets per muscle group rolls up automatically, with green/amber/red bands you can override per goal.

Per-client overrides without forking

Maya needs leg press instead of back squat? Override on her assignment. Template stays clean; her plan reads exactly right.
