Well, I just finished my first ME session on the stairmaster and holy cow that was tough. Solid leg burn the whole time. Decided to go with 40 lbs annd just 30 minutes before dropping pack annd moving to athe treadmill. HR stayed 10-15 beats under AeT. I think based on your advice I’ll do the majority of my ME indoors and have a couple strategic up & down sessions on my steep hill. Thanks again Scott!
