As a Masters-aged strongman and powerlifter, I know the importance of recovery and benefits of body tempering.  Elevate your recovery and mobility game with this printable Body Tempering / Mobility Stick — a heavy-duty, self-myofascial release tool inspired by professional body tempering rollers (like the Boomstick, DT Roller, or Forge) but optimized for home 3D printing!
 

What is Body Tempering? Developed by powerlifting legend Donnie Thompson, body tempering uses weighted pressure to "temper" (relax and strengthen) muscles, fascia, tendons, and joints. It's like foam rolling on steroids — deeper tissue diffusion, trigger point release, improved range of motion, faster recovery, and better prep for heavy lifts or athletic training.

How to Use:

1. Body Tempering Mode — Place the stick lengthwise across the target muscle (e.g., hamstrings), and have your partner press against it, and relax for 1–3 minutes per area. Add weight plates, dumbbells, or sandbags on top for more intensity (recommended 20–100+ lbs depending on tolerance).
2. Mobility / Active Mode — Put one end against the targeted muscle and push into the muscle.  For additional benefit, “floss” the muscle while under tension by moving or rotating the distal extremity. 
3. Start light — the "good hurt" should feel intense but never sharp pain.
   
   Perfect for athletes, powerlifters, CrossFitters, yogis, desk workers with tight hips/back, or anyone chasing better mobility and faster recovery.
