It’s been just over two months since I’ve tackled twenty-one. Since that time I’ve been working a push up program to improve my push up endurance. That program is supposed to get you to the point where you can do 100 consecutive push ups. Well, I’ve not reached 100 yet, but I’ve definitely improved my push up endurance and it shows in the results for twenty-one. On December 16th I needed just over 33 minutes to complete 21. Today I did it in 19:16. For those who don’t know, twenty-one is a push up and crunch workout where you start with 20 push ups and 1 crunch, then 19 push ups and 2 crunches and continue until you do 1 push up and 20 crunches. I do a leg lift crunch where I lift my legs and curl my knees up into my chest. You can do whatever type of crunch or sit up you are comfortable with. Enjoy.
By the way, I followed twenty-one with 100 squats for good measure. Squats are a quick way to burn lots of calories and you can quickly do 25 or 30 at work even. Contrary to popular myth, squats are good for you knees, just make sure you a doing them properly. Go to http://www.crossfit.com/ to see a video demonstration.
