PRE SZN vs Fitbod
Fitbod builds your workout for you. Tell it your fitness level and your equipment and each session is generated to fit, with an adaptive model that learns from the edits you make. For someone who walks into the gym without a plan, that is a real answer.
PRE SZN answers a different question. Not what to do today, but whether today beat your average.

The real difference
PRE SZN runs structured, multi-week programs: strength blocks, running and speed, hybrid race and rugby programs, each with its progression written in. Inside them, every hard set at one to three reps in reserve is scored live against your own trailing four-week average for that exercise. Beat your line and take the point. A record always pays. A full-time report closes every session.
Fitbod varies the session to suit you. PRE SZN holds the program steady so progress is measurable, then scores you against yourself on every set. Add overnight HRV, resting heart rate and sleep read against your own normal, velocity from the watch, an AI coach that reads your training, and live matches against friends.
