Optimize Zwift workouts for maximum XP

Why? You can gain more XP and therefore level faster on Zwift if workouts are specially arranged.

What? Zwift grants more XP for interval blocks than steady state, warmup or cooldown blocks. If you're getting your workouts from trainers via Intervals.icu, TrainingPeaks or creating them on your own, there are probably a lot of steady state, warmup or cooldown blocks used because that's essentially your prescribed training.

How? This tool modifies Zwift workout files (.zwo) so that they leverage several XP hacking approaches. It will not change its intensity, duration or resulting workload!
