Intro: Some of the most effective workouts are also the simplest. With the RB100 philosophy, one of the most fun ways to train is to build your own 100 rep challenge. It’s quick, intense, and requires zero gear — just your body and some grit.
Whether you’ve got 10 minutes or 30, this style of training works for strength, cardio, or skill-based goals. Plus, it’s easy to adapt for home, gym, or travel.
How It Works

- 20 push-ups

- 20 sit-ups
