Equipment: Pull-up bar, TRX bands; my TRX bands are homemade from lashing straps, PVC pipe and grip tape they cost me about $15 and took around an hour to make. The hardest part is tying the knot. Here is a great tutorial. He links his together, I just hang mine from my pull-up bar.
Warm-Up: 5 burpees, 15 crunches repeat 3x
Remember you can modify everything as needed! Can't do a pull-up? Try the first one, and then use a chair, do jump pull-ups or do negative pull-ups where you start from the top and lower yourself down. Pull-ups take time to master, so don't be discouraged! To modify pushups you can do "girl" push-ups on your knees, or put your hands on a bench to make them easier. To make them harder put your feet on the bench, or in the straps of the TRX bands(these are killer!) For inverted rows plant your feet and hold onto the TRX bands facing forward. Lean back, adjusting the angle of your lean will change the difficulty of the row. Using your back and arm muscles pull yourself forward like you are rowing a boat. Lower yourself back to the starting position for 1 rep. Complete as many rounds as possible in 12 minutes. Feel free to post the number of rounds you made it through!!
