A link to the referenced article would be nice…

When I ran cross-country, we would end every practice with a set of sprints. 5 runs, each one getting successively faster, first run being a fast jog, last one being an all-out sprint while holding your breath. We did them so that our bodies would be used to giving that final push at the end of the race, but many times that was the hardest part of our workout each day. To this day, I always try to end running, swimming, or eliptical exercise with a sprint to get the heart hammering one last time.

Woah, my bad, I’ll go get that referenced article linked.

Kevin, those last sprints were something I had to do in soccer. They were killer!

Of course, for those of us with exercise-induced asthma, a 30-second sprint out of the blue can leave us gasping for breath for 20 minutes! For just about anyone, a sudden bout of intense exercise will be easier on your system if it is prefaced with at least five minutes of moderate movement, to warm up and loosen the body before it is strained.

The recommended workout from the article of 4 to 8 sprints following a 5-10 minute warm-up, with 2-4 minutes of recovery after each 30-second sprint, would take 20 to 45 minutes, not the 6 minutes your quote from Gibala implies.

Fair enough, but I hope anyone here wouldn’t read *just* the post and craft a workout without first reading the article I’d linked to! I was selecting the most interesting part to get people to click through…
