I’m 16, male, 5′9, 160 pounds. Around 12 percent body fat last time I checked… I’m trying to get into MMA, I have really good stand up, but my ground game sucks. My motivation for all this training is that I want/need to get bigger and stronger, faster, more explosive, etc etc.. What is better train with, dumbbells or kettlebells? What are some exercises for me to do with them? Thanks for the help guys

I’m trying to workout how much work is done when swinging a kettlebell from between the legs to overhead height. The movement could be traced as a semi-circle on a straight line pretty much.
Any formula I could use to calculate the work done?
I’m not too clued up on these things yet.

Am I right in saying that the kinetic energy should equal the potential energy at rest?
As far as I understand it (using a 20kg Kb as an example starting at, let’s say, 30cm above the ground), potential energy would be

m.g.h = (20)(9.8)(.3)
= 58.8 Joules

Or am I barking up the wrong tree?
