Can I just say that this nearly gave me a heart attack!
This was murder, I was panting and hyperventilating. I had to stop countless time but I kept on going even when I thought I was going to be sick. I'm not looking forward to this workout next week at all. I just hope that none of the rest are as bad as this or I'm not going to make it too the second week.
The only thing that was good about this was the afterwards when I went in for a shower it felt brilliant after sweating so much.
