It always feels like the first interval is the hardest, followed by the next interval but the ones at the end aren’t so hard. Doesn’t feel like I’m worn out, just burning/soreness in my muscles that slowly goes away.
Any thoughts as to why this is? Is this normal? I have to lower the resistance level in TR for the first half of TR workout and raise it up for the end. Using a kicker 2018 and a pioneer full left/right power meter so I know the intervals are done at the same power output and cadence.
