Key Moments
No magic HIIT protocol: the only variable that matters is max effort
Dozens of studies show 4 minutes of total HIIT work per week matches 4 hours of steady cardio, but only if effort is truly maximal. No magic interval length or rest period exists -- 20s on/20s off, 30s on/30s off, 1min on/4min off all work equally well.
"If you're doing 30 on, 30 off, and you're just kind of going like 80, 85% through that 30 seconds of work, then you're not going to see the same results. So the one key, and Marty would say this too, is with, if you're trying to get tons of benefits, cardiovascular benefits, especially from a very, very short amount of work, that amount of work has to be like, you got to get it done. You really, really, you can't just."
Warm-up myth: 5 min on a bike isn't enough before max cardio effort
Galpin calls out the common trap of treating a 5-minute bike warmup as adequate before VO2 max testing. He recommends 30+ minute zone 2 sessions with nasal breathing, rotating between bike, treadmill, and rower to avoid boredom and joint stress.
"If I had you do the same thing with weights, you'd look at me like I'm insane. It's a blatant disregard for the difficulty of cardio work."
