I need an advanced core training workout for Jeet Kune Do/ Kickboxing and I was hoping to get some advice. Aesthetically, I'm pretty happy where my abdomen is (although my abs could be bigger) but I want to be sure I'm training my core for practicality and strength. I mix up my workout often but this is what it looks like right now:
Swiss-Ball Plank: 60 seconds
Oblique Plank: 60 seconds (each side)
Weighted Negative Sit-Up Twist (10 Lbs): 3 x 6 reps (at bottom of movement twist L & R four times)
Weighted Swiss-Ball Crunch (10 Lbs): 3 x 12 reps
Swiss-Ball Knee-Tuck: 3 x 8 reps
Thanks for any help.
