If your gym notebook had a brain.
Finally, a training app that gets hard gainers
Stop following generic programs. KeeLow uses smart progression algorithms designed specifically for skinny lifters who want to build real muscle.
Built different? Train different.
Generic apps don't work
Most fitness apps assume average genetics. They push aggressive deloads and cookie-cutter programs that kill your momentum.
You plateau constantly
Without smart progression, you're either stuck at the same weight or jumping too fast and burning out.
KeeLow is the answer
Our algorithm understands hard gainers. It's patient when you need patience, and pushes when you're ready.
Everything you need to grow
Simple. Intelligent. Designed for your body type.
Smart Progression
Double progression algorithm that increases reps first, then weight. Science-backed for maximum hypertrophy.
Confidence Scores
Every recommendation shows its confidence level. You'll always know why we're suggesting a change.
Volume Tracking
Total weekly volume matters more than intensity for hypertrophy. We track it all automatically.
High Failure Tolerance
One bad session won't derail you. We only deload when a plateau is confirmed over multiple sessions.
Weekly Reviews
Strength trends, volume progression, and bodyweight overlays. See your gains visualized.
Built for Ectomorphs
Every decision considers hard gainer recovery patterns. Consistency over intensity, always.
Three steps to consistent gains
No complicated setup. Just results.
Tell us about you
Quick onboarding: height, weight, experience level, and training days. That's it.
Log your workouts
One-tap logging. Record sets, reps, and weight. Optional RPE for even smarter recommendations.
Follow the algorithm
Get personalized weight recommendations with confidence scores. Progress at exactly the right pace.
Backed by exercise science
Not bro science. Real science.
Based on Schoenfeld et al., 2016 — mechanical tension and volume accumulation drive hypertrophy.
6-12 reps maximizes muscle growth. Our double progression keeps you in the sweet spot.
Research shows total weekly volume matters more than single-session intensity for hypertrophy.
Two consecutive sessions at top of rep range = time to add weight.
Why I built this
"I built KeeLow because I understand how difficult it is to put on mass as a skinny guy, I was also tired of 'AI' fitness apps telling me to deload when I just needed to add one more rep. This is for the people who want to track their progress, not their 'vibes', and follow a science-backed system."
