Most training apps know *what* muscle an exercise works. Bimetis knows *where* it works the muscle. Romanian deadlifts load your hamstrings at full stretch. Leg curls load them at the shortened position. They're not the same exercise. Bimetis treats them differently. BUILT ON PERIODIZATION SCIENCE Bimetis generates a complete 6-week mesocycle (8 weeks for Hybrid programs) tailored to your equipment, training split, and goals — strength, hypertrophy, recomposition, or endurance. Not random workouts. An actual periodized plan with progressive overload built in. A FIRST SESSION THAT SETS YOUR WEIGHTS Your first workout is a short calibration session — 2 working sets of each exercise — that sets your starting weights for the block. STRETCH-LOAD QUALITY Every exercise in Bimetis is rated for stretch-load quality — how effectively it loads the target muscle at full length. Your program prioritizes high-quality loading. When you swap an exercise, Bimetis warns you if the substitute compromises that loading. BUILT AROUND YOUR GYM Tell Bimetis what equipment your gym has. Your program is generated for your actual setup — not a theoretical fully-equipped facility. Barbell, dumbbell, cable, machine, or bodyweight — Bimetis builds a real program for what you have. INTELLIGENT SWAPS Can't access the cable machine? Barbell rack taken? Bimetis rebuilds the session in real time, scores the biomechanical similarity, and preserves your mesocycle's phase structure instead of just improvising a substitute. You always know what you're trading. PROGRESSIVE OVERLOAD TRACKING Double progression with automatic overload suggestions. Bimetis tracks your sets, reps, and load to advance your program week over week — not just suggest a random weight. WHEN YOU STALL, IT NOTICES If your strength on a muscle stops climbing, your next block upgrades that muscle's exercises to ones with better stretch loading. FRESH EVERY BLOCK Each new block rotates in different exercise variations for the same goal, so your training stays fresh. SUBSCRIPTION Free for 14 days, no card needed.
