After a few years of working out, my friend Chris Hooley & I got bored at the gym, so we decided to challenge ourselves a little differently…to push our boundaries, test our endurance and change things up. I know there are other fitness junkies out there like us that want to push their limits. To those, I challenge you!

Below are the first 30 of a 100 day fitness challenge.  You will fail at some of these challenges, but that’s okay as long as you give it your all (I estimate a 75-80% success rate).

• Chest/Arms – 1,000 push-ups in a day
• Shoulders/Back – 100 pull-ups in a half hour
• Back/Legs – 100 good mornings at 100lbs in a half hour
• Shoulders/Back – 100 headstand pushups
• Core – 500 sit ups in a day
• Cardio – Spend 60 minutes on the stair stepper machine
• Arms – 250 tricep dips in a day (not chair dips, full body weight)
