Yeah about 2-4 times a week.
It's not for everyone though.
For example here's a typical night for me:
warm-up stretches
1. 3x15 calisthenics lunges (normal)
2. 2x10 calisthenics lunges (transverse plane)
3. 2-3x pull-ups
4. Squats (front / back) depending on how I feel
5. Overhead press / Clean (alternate between sets)
5b(optional). Bench press I'm not a big fan of benching, but I'll randomly do a couple sets of 225...depending on how I feel...
6. calisthenics tricep dips 3-4x
7. tricep pulldowns 3x
8. pull-ups subsetted with resistant pushups on medicine ball 3x
9. DL or barbell rows...
It's weird I do a modified version of SL. Interestingly enough, it takes me less 45 minutes to complete this regime. I plan my workouts away from prime time hours. When I leave the gym I'm not particularly sore either, nor morning after. I'm immune to soreness
