When you have to bring your leg up with a chamber all of the time, our core is what does that, your stomach does that.
The abs work is accomplished by situps or crunches and leg lifts with the legs at different elevations, with the knees drawn up, together and separate.
Doing situps while twisting the trunk and trunk raises while lying on the side target the lateral, or side core muscles.
Isaacs advocates various forms of situps including an inverted situp in which the athlete brings his knees to his chest and then kicks his legs out, and flutter kicks as well as the standard plank.
Core training can also incorporate weights, resistance bands and exercise balls, but one of the pluses is that the training can also be done without any equipment at all.
The physical benefits, of course are greater strength as well as improved speed.
And then also for martial arts, it helps you with your kicks.
You have to move your legs up and it helps you with your striking technique because you have to turn your torso to get power in your upper body.
If you are a goal-setting athlete—and what martial artist isn’t pursuing a higher rank, a different colored belt or a championship? – core training can help by strengthening all the muscles in the torso, front and back, which improves balance and alignment.
Almost as a consequence of training, most upper level athletes, from martial artists to football players, develop a strong core.
