Oh I love this thread. It's singing to me. I didn't get into kettlebells until I was 40 back in 2009. I call it the great, the good and the ugly.
First, the great, I fell in love with using them and made terrific gains. I learned to lift correctly, got into even better shape and had a passion.
Second the good. I was really good at it. I'm a 190 lb. guy. TGU's with an 88? No problem, ETK up to 80K? 165 on a 10 minute snatch test? Check Check Check. Doing workouts with double 70's sure.
THE BAD....I was too old to try to keep up with mutants in their 20's and 30's. Between sports and TRAINING VOLUME, I wore the cartilage in one shoulder out and arthritis in the other. ETK is not a program for older athletes. Neither are doing 200 snatches. If someone wants to do the Giant, I'd tell you to stick to 20 minutes.
So, to answer the question. What I'd do over again?
For barbell, if you can't do 225 for 10, you shouldn't do any more weight. 10 RM is best for most exercises.
If you can't do an overhand grip on a deadlift without straps, it's too much weight.
Volume 25-40 reps. 50 on a good day
3 strength workouts per week, total body, just do a different exercise
5-10 minutes yoga 4-5 days a week. Butterfly pose, Pigeon pose, Lying twist, Seated fold forward, Standing fold forward, Child's pose, Down dog, with heels touching ground.
Watch my diet and rest more.
