The 100-Rep Full-Body Workout Challenge

High-volume training is a powerful way to push muscular endurance, elevate your heart rate, and build resilience across all major movement patterns. The 100-Rep Full-Body Workout is a compact but brutal test that targets every key area — legs, core, back, chest, and shoulders — in a single dose.

This RB100 Challenge is ideal for:

  • Those with limited time but high intent
  • Athletes seeking functional capacity development
  • People who love testing themselves against volume thresholds

The Structure

Pick 5 compound exercises that cover push, pull, squat, hinge, and core. Perform 20 reps of each for a total of 100 reps.

Example Workout:

  • 20 Goblet Squats (legs/core)
  • 20 Push-Ups (chest/triceps)
  • 20 Bent-Over Rows (back)
  • 20 Reverse Lunges (legs/balance)
  • 20 V-Ups or Plank Shoulder Taps (core)

You can structure this as:

  • 5 rounds of 20 reps (one movement per round)
  • 2 rounds of 10 reps each, circuit style
  • For time (advanced)

Rest only as needed between sets.

“The reps don’t just build your body — they build your tolerance to discomfort.”
— RB100.Fitness

Scaling Tips

  • Reduce reps to 10–15 if new to strength training
  • Use light weights or bodyweight
  • Swap movements for mobility-friendly options
  • Focus on form over speed

Progress Over Time

  • Record your time or rounds completed
  • Repeat weekly to track progress
  • Add weights or reduce rest as you adapt
