Every move on this site is one I coach and train myself.

I am a personal trainer, and I wrote the app this site is about. The short version fits in a line. The longer one matters more if you are deciding whether to trust a workout you found on the internet: every session in StepInside is one I run myself, and every form guide here says what I would say to you standing in the room.

Built around not having a gym

Nothing in the app needs equipment. Across every session the only things ever asked for are a wall, a sturdy chair or step, and something soft under your knees — and most moves do not want even that. That is a real constraint, and the constraint is the interesting part: with no weight to add, what is left is leverage, tempo and time under tension. So the leg session is a slow tempo squat, a wall sit and a glute bridge hold rather than a heavier bar, and it is the session people find hardest.

The same move, at the difficulty you are actually at

"Do a push-up" is useless advice to half the people who read it, so the push-up is in the library more than once — on your knees, with your hands up on a chair, flat on the floor, hands close together, feet raised. Same for the squat and the plank. You are meant to start below where your ego puts you and move up when the form holds, which is slower than most programmes admit and the reason people stay with it.

Two of the eight sessions are easy on purpose

Six minutes of mobility and seven of breathing and stretching are not filler between the real workouts. They are in there because the week you are actually going to have contains days you slept badly, days your back is tight, and days you will skip entirely if the only option is a hard one. The core work follows the same logic: holds and anti-rotation, no crunching, because bracing under load is what a core actually does when you are not training it.
