Week 2 day 4 of X2

Hey everyone, I did the total body workout for the second time today. I am getting better at the moves, but still have to modify some of them. I still cannot do the triceps kickbacks on the stability ball with all the weight on one arm. I have to lower one knee to the ground and even then it still rolls around quite a bit. I managed to get my heart rate up enough between that an ab-ripper to burn about 500 calories. I am definitely not one who will complain about the lack of traditional cardio. I have to keep this a short one, but if you have any questions or comments you can leave them and I will reply when I get the chance. Thanks for reading!
