Herschel Walkers Amazing workouts

This morning I came across a atricle about Former NFL Star Herschel Walkers crazy workout routine and his use of body weight exercise. Its inspiring to me starting off and amazing that he could do it so long at such a high level and still does it everyday. I could never do 2,000 pushups and situps a day like him and eat only one meal a day at dinner time. But it worked for him and he proves that bodyweight exercise can be just as good as weights and barbells.
