Gaining strength, muscle or endurance?

Jeff asked this question after my week 4 day 2 hundred push up workout:

What kind of gains are you seeing? Strength, muscle or endurance?

Strength is improving. I'm adding more weight to my bench work, even though I'm doing it less than 20 minutes after my push up workout.

Muscle mass is increasing. My wife pointed it out to me, then I notice my shirts are getting tighter across my chest.

Endurance is the most dramatic gain. As you see from my week 4 day 2 workout chart, I've gone from struggling through 48 pushups the first day to over 100 pushups now.

A whole week of workouts takes only 30 minutes. I've been doing one hour of weight training 1-3 times a week for over 4 years. This program is pretty effective at breaking through my chest and shoulder plateau.

I invite you to join me in the hundred pushups challenge. You can only lose 30 minutes a week. If you start with only 5 push ups, I guarantee you will enjoy an even higher percentage of improvement than I am. If you're already a strong guy or gal, you still might be able to double your current number of pushups.
