Bring on 40's

In honor of David finally reaching the decade of great wisdom, and fitness, I created a combination of exercises incorporating 40 in as many ways as I could think of:

1. 4:00 of stationery cycling
2. 40 double unders
3. 40 burpees (ouch)
4. 40 situps
5. 40 lunges
6. 40# arm one (with gym equip.; basically a push-press)
7. 40 bicycles
8. 40 squats
9. 40 pushups
10. 40 crunches
11. 40 pull-down thingies in the gym with, naturally, 40 lbs
12. 40 sec plank
13. 40 sec left plank
14. 40 sec right plank

Happy Birthday!
