TESTIMONIALS & REVIEWS


“I have never felt more connected, powerful, and more capacity rich to do so many boulders on a trip.Your training plan and eye opening advice unlocked new gains for me that are so inspiring.”

- John Yu


Your program was largely responsible for my latest successes. On my 40th birthday I climbed a V11 and a V9 in a single session. At 40 years old I feel I am truly a better, stronger, and most importantly, a healthier climber because of what your programming has taught me.”

“I sent the rig, Tell Tale Heart 5.12b in four tries!! I want to say Thank You. My goal with starting this training was to send 5.12 more consistently and quicker and I have basically tripled my 5.12 ascents this year with significantly less effort.”

- Eric Danner


“I've done the Tier 3 program two years in a row now, and both times I've seen an insane amount of growth. I recently completed the second round and feel like I have unlocked a new level in my climbing. As someone with a really busy schedule, this program was crucial to leveling up my climbing skills. I always looked forward to training and Leif was such a great coach to work with. He understood where my weaknesses were and created a program that has helped me get out of a plateau I have been in for years.”

“It was really nice to get introduced to some climbing specific training. Your response time was always quick and thoughtful, which made a huge difference.“

- Nils Mindnich


“Although I'm always interested in benchmarks, I'm also 115% sure that I'm climbing better and feeling fitter after the program. Everything from the drills, to the exercises were great. Despite climbing 17 years, I’d never trusted myself to do deadlifting, hangboarding or use campus rungs and it's been wonderful to find out that my body holds up to the challenge. And feel stronger on the rocks. I also enjoyed the drills and climbing problems far more than I expected.”

- Geoff Brennan


“I just finished the 24 session program and I loved it! Not only did I have fun while training (basically a miracle), I saw a ton of growth in my climbing. Leif did a thorough assessment and was flexible and easy to work with. He switched up the program to tailor to growth he saw in my performance, and allowed me to adjust things that weren't working. He helped me address some specific weaknesses that I've struggled to train before. I also saw huge strength gains over the course of the program without any injury, strain or tweaks that I've typically experienced before when training hard. I can't wait to use what I learned outside. I would definitely train with Substr8 again.”

“I learned a ton about more focused training and feel like I have a good foundation for continuing on my own for a while.”
