The SID AI that turns every workout into progress — and every week into proof.
Free to start. No credit card required.

You want to train smart, but the options are either free-and-generic or expensive-and-inaccessible.
Personal trainers cost $60-150/hour. That's $500+ a month for consistent coaching that most people can't sustain.
Free programs don't account for your injuries, equipment, schedule, or when you've hit a plateau. One size fits nobody.
You watch a YouTube video, try the exercise, and hope for the best. Bad form becomes bad habits becomes injuries.
Enroll to build your athlete profile. Then train with an AI coach that knows everything about you.
SID learns everything about you in one smart onboarding. This isn't a form — it's a conversation with your future coach.
SID tailors every rep to your specific goals
SID tracks these over time to measure real progress
Private & encrypted. SID uses these for monthly visual comparisons.

Beta testers who trained with SID before anyone else.
“I was stuck at the same bench press for months. SID adjusted my volume and deload timing, and I broke through in 3 weeks. No human trainer has done that for me.”
“As a complete beginner, I was terrified of the gym. SID gave me a program I could follow confidently and explained everything I asked. It's like having a patient coach in my pocket.”
“The form check caught my knee cave on squats before it became an issue. I've spent thousands on trainers who missed that. SID spotted it from a 10-second video.”
