[SlowAndSteady]

I’m surprised that inside a gym would be warmer than outdoors in any time outside of Autumn and Winter.

 

anyways, I’m wondering the same as my heart rate at  a given intensity can vary 20-25 beats on a cold vs hot day. What I’ve been doing is still trying to stick to the zone 2 heart rates…. So on hot days I just slow down dramatically. But not sure if that’s what we are supposed to be doing
