Great exercise machine

It seems like my personal trainer came up with a new exercise

Somebody know what exercise the best for the buttocks

I am craving for some exercise

I hope you can imagine my puss while I exercise

Exercise with me ?

the exercise is having an effect

Let's exercise together

What’s the name of this exercise?

a little dance before exercise

Now I understand why my trainer likes me to do this exercise.

Is that a good exercise?
