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 trying to get tons of benefits, cardiovascular benefits, especially from a very, very short amount of time, it has to be maximum effort. Like, nope, you got to do the work."
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."
