In a competition, your physical and mental limits are tested. Lung burning, heart rate max-ing, muscle fatigue, and pain tolerance readjusting are all part of the deal. So a quality pre-fight conditioning session should also strategically expose you to this. When you feel like quitting half way through, you know you're on the right track.
Eventually, you learn how to DANCE in the FIRE of DISCOMFORT.🔥🔥🔥
Soul-testing cardio is difficult to do alone. That's why even conditioning coaches need a conditioning coach.
