Let him have a go at it! Let him do what's fun and natural for a kid his age to do. I think that especially for kids if they get into the mindset it's "working out" they might get bored or just not like the idea of it after awhile. If you both just have fun doing it it will become a great bonding experience for you while getting in better shape. And the memories of playing in the park with his dad will be fantastic!
I NEED Sunshine! And a beach would be nice too!
