Back in the Gym

08/06/13
Scientific warmup
50X43.2 squat
50 pushups
Stretching cooldown
After about thirty squats I was feeling some strain on my lower back, I'm not sure why though. I kept my weight over my heels, my back straight, and my eyes forward. My legs felt good throughout. The first thirty pushups were easy, the next ten were difficult but the last ten were very hard and I barely struggled through them. I think I should introduce exercising to exhaustion in my workouts, at the end if each workout I will choose an exercise and perform it to failure.
