Why Fit4T

Built for Strength

Most home machines and hotel gyms are built for cardio. Fit4T is built for strength. Born from the need for real resistance training in small spaces and short time windows, the exercise library is packed with strength and resistance moves you can do with minimal or no equipment. Hotel room, living room, crowded gym floor – your workout goes where you go.

Your 4 T's

You design every workout around four choices:

Stopwatch icon Time Pick 15–45 minutes – warmup and cooldown built in
Heartbeat icon Tempo Go Standard, Turbo, or Extreme – whatever you're feeling that day
Bullseye icon Target Focus on upper body, lower body, or go whole body
Dumbbell icon Toys Add up to 8 equipment types, or stick with 50+ bodyweight-only exercises
HIIT Mode workout design screen showing Time, Tempo, Target, and Toys customization
Reps Mode workout design screen showing Tempo, Time, Target, and Toys customization
