Proof. In Their Words.

Remarkable improvement at 71.

Working with Sid has been a life changing experience. I'm 71 and struggle with carpal tunnel and arthritis in both thumb joints. After 6 months of online classes following the ATG system the improvement has been remarkable.

From one round to six. Pain free.

I'm 45 and started working with Sid three months ago. I had given up the thought of being pain free after a single round of golf. Today I play six days back to back, work out, and I am pain free.

Regained a sense of freedom.

Sid's programming has given me back a sense of freedom in my body. The attention to detail in each session and the structure of the long-term plan is unlike anything I've worked with before.

120 sessions in. Pain gone.

After 120 sessions with Sid my chronic lower back pain is gone. I move better at 52 than I did at 35. The program is meticulous, the coaching is direct, and the results compound.

Better than before.

I came in post-surgery and worried I'd never lift the way I used to. Twelve months later I'm stronger, more mobile, and moving better than before the injury. Sid built every step of it.

I'm Sid van Raadshooven. Rehab specialist, ATG L2 coach, strength coach, ex Muay Thai fighter.

I rebuilt my own body after a serious knee injury that should have ended my career. Ten years later I've turned that obsession into a system for lifters, fighters, runners, and anyone who refuses to spend the rest of their life negotiating with pain.
