Some of the best fitness tests are deceptively simple. The 100 weighted step-up challenge is one of them.

Whether you’re training for mountain trails, sport performance, or just want rock-solid legs and lungs — this is a go-to movement. It’s scalable, effective, and totally unforgiving. You’ll get stronger, leaner, and more resilient with every rep.

“Want strong legs and lungs? Step up, don’t look down.” — RB100.Fitness


The Challenge

Complete 100 total weighted step-ups:

  • Use a platform height of 16–24 inches (40–60 cm).
  • Alternate legs every rep or do 10–20 reps per side before switching.
  • Use dumbbells, kettlebells, or a weighted vest.

Beginner Option: Bodyweight only — 100 reps still hits hard.

Advanced Option: Add 10–20kg and time your total duration.


Why Step-Ups?

Step-ups are a staple for good reason:

  • Unilateral strength for balance and coordination
  • Targets glutes, quads, hamstrings, and calves
  • Boosts grip, posture, and joint stability under fatigue
  • Doubles as a conditioning challenge when unbroken

This is a favourite among military prep programs, CrossFit athletes, and trail runners.


Programming Options

  • 10 sets of 10 reps with rest between
  • 50 reps per leg, unbroken
  • EMOM: 10 reps every minute for 10 minutes
