It’s good for you. It’ s a bit different then the one you do at the gym.
You have plenty of fresh air.
You may need to get creative.
You can run/bike to the site (playground or park), which will serve as a general warm-up.
You will have to run/bike back from the site, which will serve as a nice cool-down.
It’s green, environmentally responsible and fun. You may meet new people at the park and make new friends too.
One big benefit. Just DO IT .
