Agreed, my legs are usually screaming at me. I need to get better at working through the screaming, despite having done this type of training for a while.
Speaking of legs during hard intervals, yesterday I did some 30/30’s and my right quad seemed to be more fatigued than my left as things got really hard. I’ve always assumed I was right dominant, but I now have a left only pedal power meter with my Hammer and my power was consistent on both measurements. Makes me wonder if it’s a physiological thing or a fit thing.
