You're working against your own body — and you probably don't know it.
You can spend $1,000s on a bike and all the right gear. But if your muscles are imbalanced, you'll never reach your full potential. Worse — you're at risk of injury.
Whether you sit at a desk all day or log hours in the saddle, your muscles constantly adapt to shortened positions — a process called Muscle Adaptive Shortening. Over time, muscles that aren't used through their full range of motion literally shorten to the length they're habitually used at. The #1 culprit: the psoas (so-as) — the muscle that connects your upper and lower body and drives nearly every movement you make.
When the psoas shortens, it pulls the front of your pelvis down and forward — a condition called Anterior Pelvic Tilt. This rotates your spine out of neutral, collapses your core, rounds your shoulders, and weakens your glutes. On the bike, that means less power transfer, more strain on your lower back, and a position your body is constantly fighting against.

Do you suffer from any of these?
- ❌ Tight hamstrings and hip flexors
- ❌ Knee pain during or after rides
- ❌ Lower back pain in the saddle
- ❌ Can't get low or hold your position on the bike
- ❌ Feeling stiff, slow, or limited no matter how much you train
Then you likely have Muscle Adaptive Shortening. The good news — it's completely fixable in just 20 minutes a day.
