Feels unbelievable pushing myself with cardio like this. 185 BPM on walking incline warmup, 202 max on 30 second sprints. Haven't been able to do this since my mid-20s and I'm just getting started 😀
@nevrekaraishwa2 I'm paying for Coursera (not trying to counter this post's topic) - there're seemingly endless topics you can get certified in by legitimate entities.
