@Mbaker . Sounds like a good routine there. Like the idea of moving the blood/ oxygen requirements throughout the body in a short space of time.
Not to long ago I was doing a 10 exercise, 10 rep , 10 minute routine. Gruelling but fun. The way it was structured made it doable but quite demanding.
Have to admit that nowadays I steer away from the heavy weights. Age, old joints especially, shoulders make for a longer than acceptable recovery time required
Much prefer HIIT and Tabata training nowadays. Heart and lungs over pecs and bi’s
