VO2 Max Interval Workout Substitutions

I feel like I’m drowning (as in …literally…starved of oxygen) in the latter parts of any interval now.

Congrats! You’re doing it right!

I’ve read that VO2 intervals are akin to drowning, and apparently I’m not the only one:

For VO2max workouts, sometimes you need to increase the scaling a couple of percent, sometimes decrease, depending on your fitness profile. You should be “drowning” toward the end

Several reasons for what you’re experiencing but what you suggest is a good route. VO2 can be a wide range, so find an interval length and intensity which is repeatable and dig in. Once you are “good” at those, increase duration and embrace the drown!
