One of the most standard exercises for any workout routine, the push-up is pivotal to your training as a martial artist. Legend has it that Bruce Lee used to do push-ups with just his index finger and thumb. While that may be out of your league, using the push-up to develop your strength and endurance are important to both your striking and grappling. Another benefit is that you can use this exercise anyway, as it requires no type of equipment. Mix this workout into your training program when you are working on your chest and arms. As you become stronger, use variations to improve the intensity of the exercise.
