@mr_loevinger Currently I always start with an extended warm up, then S&S and then I add other exercises to taste. This makes the routine entertaining and low threshold, because on the off days, I'll just do the minimum and be happy with it. On better days I can add a lot of exercises and I can be sore the days after. I combine kettlebells with a set of gymnast rings, a couple of the fun additional exercises I do:
Rings:
- pull-up & its variations: scapula only, negatives only, top hold, bottom pauses
- hang variations
- toes to rings or toes to ceiling sometimes with upside down rows
- skin the cat
- support holds (working my way towards dips)
- ring rows (sometimes with false grip)
- ring pushups (highly recommended!)
KB:
- farmer/waiter walks
- bent over rows
- cleans & snatches
- lunge & squat variations
- pull throughs
On a sidenote: you're stating you're focused on biceps, but for big arms you need big triceps. In any case, adding pushup & pullup exercises to the S&S program will be OK for you, especially since you're relatively new to exercising, you won't easily get overtrained.
