BYGG Fitness

BYGG writes you a six-week strength and hypertrophy program from what you actually have — the equipment you can reach, the days you can train, how long a session can run, and what hurts.

Not a template you adapt yourself. The program is built around your answers.

How it works

You answer a questionnaire once. Equipment, schedule, training history, injuries, goals. It takes about five minutes.

BYGG writes six weeks around your answers. Every session, every exercise, every set.

You log what you lift. Next week's targets come from those numbers — not from a plan written before you started.

In the gym

Big numbers you can read at arm's length.

A rest timer between sets.

A swap button for when the rack you need is taken. Swap and the program adjusts.

Sets log offline and sync when you're back online. No signal in the basement is not a problem.

Tracking

Every set you log keeps the weight, the reps, and how hard it felt.

A body map showing which muscles the week is built around.

Body measurements — chest, waist, hips, arm, thigh, calf — in inches or centimeters.

Progress photos, private to your account.

A share card at the end of a session if you want to post it.

What it isn't

BYGG is not for everyone, and that's deliberate.

There's no social feed, no leaderboard, no streak to protect. No AI chatbot. No promises about how you'll look in six weeks.

It's a training tool for people who want to get stronger and would rather have a program than a workout.
