StrengthBox: Workout Tracker

StrengthBox is the workout log for people who lift. Log sets in seconds, follow programs that add the weight for you, and watch three white lights come on when you hit a new record.

PROGRAMMES THAT DO THE THINKING
• Ready-made programs: 5/3/1, StrongLifts 5x5, PPL, Upper/Lower, Full Body, PHUL, Arnold Split, German Volume Training and more
• Automatic progression: make every set and the weight goes up next session; miss and you repeat it
• Percentage programs worked out from your max
• Build your own, or follow one your personal trainer sends you

FAST LOGGING ON THE GYM FLOOR
• Sets, reps and weight in a few taps, with last session's numbers alongside
• Plate calculator that shows exactly which plates go on the bar
• Rest timer that starts when you tick off a set
• Supersets, AMRAP, EMOM and For time with their own clock
• Cardio intervals, like 6 × 400 m

HYROX-STYLE HYBRID RACE
