Everyone in our family owns a bike, so we all go on family bike rides nearly every day. We take a picnic dinner with us. The kids don't go fast, but I just adjust the gears so I'm getting a ton of resistance with every pedal.
We also walk to places we normally drive like down to the store or the park. There are also tons of amazing hiking opportunities for us that are very kid friendly. Shove 40 lbs of rocks in your pack. I'm not kidding, this is how I train for longer, overnight hikes.
You an burn a ton of calories playing with kids. Jumprope, tag, football, basketball . . My kids love doing exercise videos with me and they're better at it than I am.
Hope those ideas help.
