This program is built around a garage gym. Make sure you have consistent access before starting, since the progression model assumes you can perform the same movements week over week.
Each session typically takes around 60 minutes to complete. That estimate covers your working sets but doesn't account for warm-up or rest between sets, so budget a little extra time when you're first learning the movements.
5/3/1 Leviathan Mesocycle is structured around 4 training days per week, with rest days built in to allow for recovery. The Boostcamp app lets you reschedule sessions if your week doesn't go to plan.
The program runs for 10 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.
