Not sure on your fitness level, but assuming you have a little cardio base built up: Flipping tractor tyres end over end can be a really good workout. You could also do that footwork drill for cardio where you hop your feet in amd on different tires. I think searching “crossfit tires” would give some other good ideas.

Also, the rural community I grew up in had a cycling community that would go on bike rides in the morning. Are the roads around where you live safe enough from cars to cycle a bit? Maybe that could be an option. Same for jogging.

As for finding time, really you’re just going to have to choose a time and do it. Early morning workouts are the gold standard for people that work full time.

Just saying, if your goal is to lose weight, you’ll be better off focusing on your diet.

Just wanted to say, thanks for hosting this instance! I’m a reddit refuge and this Lemmy instance has been really straightforward on how to get started.
