March 6th Workout
Here is the workout I did last night. You need a weight (they use a sandbag, but I have a 10-lb ankle weight with a strap which worked just fine), and a surface for your feet during the elevated plank knee tucks (I used a chair, but a couch or stability ball would work well, too). This workout is actually supposed to be 50 reps each move with 500 skips at the end, but I misread and only did 20 of each. When I didn't feel dead afterwards I looked and saw that it was actually 50 (!) so I repeated once more. That did the trick.
Happy sweating! (and panting, and cursing :) )
