Late reply. Sorry, just wasn’t sure how to answer. I started a training log here Starting at Age 52. So this wouldn’t fit into my immediate plans. I wasn’t think of CrossFit. Turns out “complexes” is what I was thinking of, but I didn’t know there was a name and method for it. A few years back when I first got a light barbell set I would just heave the bar up, press it a few time, set it behind my neck squat it a few time, deadlift it a few time, until I was out of breath, then put it down and repeat after catching my breath. Sort of like a complex, but now I realize my clean isn’t right. When I move on from my current plan I was thinking complexes would be good for maintenance. For some reason I did them intuitively, I figure I should eventually learn how to do them correctly after building a better strength base.
