Strength, Built Over Time
One Arm Tires First. One Side Looks Smaller. You've Noticed It Too.
Left alone, small side-to-side differences tend to grow — the stronger side takes over, form slips, and progress stalls.
Muscle Imbalance Score shows you exactly where you're uneven — then builds an ongoing plan to fix it and keep building strength, in sessions of one hour or less.

Why I built this
It started with a pulled lat.
I pulled a muscle in my right lat. Stopping training wasn't what helped — adapting it was. Working with a professional, I learned about contralateral training: keep training the uninjured side, because it supports the recovery of the injured one.
Rehab was slow and deliberate. Then it turned into a normal weights program, built to keep building real strength without flaring the injury back up.
That was over a year ago, and it's still going. It's a long game, not a quick fix — that's where "Strength, Built Over Time" comes from.
The hard part was the back end. I have a job and a life, so every session had to fit in about an hour. No program I found was built for that and for an uneven body. So I built one.
