I’ve been doing this workout for several weeks. Really liking it. Pull the tire 10 times, jog for about 1/8th mile, and repeat. I do this for between 60-90 minutes. A few points of flexibility with this workout I like: pull heavier, jog harder, and wear the Elevation Training Mask. The video isn’t very climactic. It’s more for illustrative purposes.
By way of lots of experimentation at various altitudes with my friend Joe, I’ve learned not to take Elevation Training Masks too seriously.
