I've noticed that as I do more NC WO's I get 'activated' more quickly. It usually just takes me 10-15 mins max to feel like I really want to tear up some serious weights and that's where I stop. I do 3 NC WO's / week.
I have also noticed that I am getting more efficient at some of my exercise choices. I.E. Medicine ball push press throws. I do this with a 15lb ball inside the basketball court at my gym, today I came close to hitting the ceiling on my 3rd set which is about a 8' improvement since I began. Also doing jumps up the staircase, like a standing broad jump but UP the stairs so there is no impact on landing, kind of like a box jump but continuously up the stairs, resetting on each landing. I can take 4 at a time, gets some strange looks but it feels great!
I rotate exercises every NC WO - never the same, but favorites are the stairs broad jump, med ball slams and push press w/ ball.
