This 45-minute muscle building workout focuses on compound strength moves with longer work intervals to drive muscle growth at home. It opens with a short warm-up, moves into a 6-exercise circuit you repeat 6 times, and finishes with a cool-down stretch.

Hit start and the built-in timer calls out every exercise and rest, so you never have to look at a clock. Switch the level below to make it easier or harder.

FAQ

Is a 45-minute muscle building workout enough?

Yes. 45 focused minutes with minimal rest is a complete session. Consistency matters more than length: doing this regularly beats an occasional long workout.

How often should I do this muscle building workout?

Aim for 3 to 4 times a week, leaving 48 hours before training the same muscles again. Increase the level once the current one feels easy.

Can beginners do this workout?

Yes. The beginner version uses easier exercise variations and longer rest. Move at your own pace, and keep good form over speed. Pause the timer whenever you need to.

Do I need any equipment?

A single kettlebell. Most people start with 8–12 kg (18–26 lb) for swings and squats, and some moves use bodyweight only.
