I’ve done yesterday the first ME workout. Warmed up for 20 minutes , then 40 minutes of stairmaster carrying a backpack with about 12%BW.
My HR was between AeT and AnT throughout, varying by as much as 10bpm. I felt a light muscle burn, but I’m not sure if the weight, stairstepping speed or duration were appropriate. Today I don’t feel any DOMS, nor are my legs more tired than a usual post workout day.
