Goal is a low impact total body work out for male in is early 40’s. Lean muscle, not mass. General weight maintenance.
Past shoulder and knee injuries so low weight, higher reps.
Would be combined with intermittent cardio with bike, elliptical, swimming mostly.
I don't do a lot with KBs but one of the moves I like best isn't a swing, it's goblet squats. Work your way up to the heaviest weight you can use and still do 3-4 sets of 10-12 and you'll feel it. Works a lot of different parts of your body too.
Forgot to mention, I've got one shoulder that'll need surgery in the next year or two, a little arthritis in one knee from a skiing accident, and a fused ankle on the other side. Goblet squats don't tweak any of those, but I do use a plate under each heel to elevate the heels about an inch and a half. That makes any kind of squat easier on the knees.
