Does this sound like your "Core Workout"? 100 Crunches 100 Decline Sit-ups w/25lb plate 100 Side Bends w/45lb plate (50 each side)
If this sounds like your "Core Workout", then it is the same exact "Core Workout" that bodybuilders 20-30 years ago did to look good in front of the mirror. We all would love to have a 6-pack, but our training should match our goals. If my goal was to run a marathon, I wouldn't run 1-mile/2x's per week.Training doesn't match your goal.
Becoming the Jiu-Jitsu Athlete
To become the best BJJ athlete that you can be, you must always look to improve upon your total body strength, core strength, and overall endurance. As a BJJ athlete, working out is not only beneficiary for your health, but helps to improve your performance on the mat. I am sure that there have been plenty of times that you have been rolling, in your academy or at a tournament, and you just felt gassed. Have you ever asked yourself the question, if you trained the right way, meaning, a specific type of training for which your body needs to train in order to help enhance performance; could you have escaped the attack? Finished your opponent? Or even just stayed more competitive?
