2. Fetch tease for abs
Crunch and tone your tummy while your dog sprints to play fetch.
How to: Grab your pet's favorite fetch toy and get down on the floor in sit-up position. Hold the toy as you do a sit-up, and pretend to toss it as you reach the top. Fido will chase after it, only to realize you still have his toy. Do another sit-up, and pretend to toss the toy again. Try to get in as many reps as you can until your dog stops chasing and playing along.
