I've included some links below which include simple and easy ways to have green workouts: 1) use metal bottles instead of chucking the plastics every day, 2) use recycled gym mats, 3) go to a gym closer to home and walk there, 4) exchange/swap used equipment and lots more.
Then there's eating green to save our planet too. 1) How about going vegan? If that's too hard, 2) how about ordering less takeout, 3) compost uneaten food instead of putting it in the trash, 4) buy food in season and buy local?
