5 day challenge done!

Hey guys! I've just completed day 5 of the 5 day challenge to burn fat and build lean muscles and I feel great :) I really enjoyed this challenge , I liked day 2 and 5 the most while day 3 was really hard but I managed to complete it without resorting to any modification ( yay!!).

I wanted to know if you guys have tried this challenge and what you think of it: what was the day you liked the most? What was the hardest ?

Have a nice day :D
