Bottoms up pressing a kettlebell has nothing to do with shoulder health, it's a movement that challenges the wrist. I have very healthy shoulders, being 24 and never having any pain in my shoulders for 10 years of weight training and I still can't press BU KB press 90% of my one handed press (40 kg). I managed to do 26 kg.
Competition rules bench press: 110 kg x 1; 120 x 1 (ugly JM press); 120 kg x 1 perfect
Mini band triceps extension: 12 x 3
Pull ups: 15, 12, 10
Mini band shoulder press: 12 x 3
I stripped down the weight, this was my last session and I'm feeling strong and ready, 22nd of September is the date of the competition, just keeping the weight down, resting and getting ready to give it my all.
A good indicator of healthy shoulders is being able to bottoms up press at least 90% of what you can press normally. I don't yet have heavy kettlebells so not sure what I can do but definitely not 40kg that's pretty solid.
