Few movements are as satisfying or as brutal as the med ball slam. It’s a pure expression of controlled violence: lift, explode, reset, repeat.

But this challenge isn’t about one powerful rep. It’s about doing it 100 times. That means maintaining power, form, and focus while your heart rate climbs and your grip starts to fail.

This RB100 Challenge brings together cardio, core power, and stress relief in one high-intensity blast. If you’ve never hit 100 slams before, you’re in for a full-body wake-up call.

Why Med Ball Slams Matter

Med ball slams train:

  • Core-to-ground power transfer
  • Triple extension mechanics (hips, knees, ankles)
  • Rotational control and anti-flexion
  • Grip strength and work capacity

Plus, it’s one of the most therapeutic movements in training both physically and mentally.

Slams have been shown to improve explosive output and reduce sympathetic stress when performed at high intensity and short intervals [Journal of Strength and Conditioning Research, 2020].


Programming Ideas

  • As a finisher: after lifting or sprint sessions
  • EMOM: 10 reps per minute for 10 minutes
  • In a circuit: combine with #68: Push Presses or #76: Double-Unders
  • Paired with a core isometric: slam + plank hold

Technical Cues

  • Keep elbows slightly bent don’t lock out
  • Use your hips and abs not just your arms
  • Exhale hard during the slam to sync breath with force
  • Land with soft knees and braced core to avoid jarring impact
