Lastly, today, we will work on your abs. It's what will make you slim and please Miss.
Lift your legs in the air and then, on every repetition, you will lift your shoulders off the ground and move your hands towards your feet, just like on the picture.
You will do 4 sets of 15 sit ups.
Rest only 15 seconds between every set.
You may NOT linger on the ground too long between repetition.
Try to control your descent after every repetition. It's the part with the best benefit.
Once this exercise is over, continue.
