Getting into shape is like 60-90% diet, depending on who you talk to. personally, that's the hardest part. Chipotle is so good.

I used to go to boxing classes pre-pandemic. Think of it as glorified zumba. We're really punching bags and shit, but not in a ring and not sparring. just following an hour-long workout. But, it did give me a good foundation of things that are helpful to workout WITHOUT weights. Body-weight exercises can be powerful and all you need is space to do it.

Jumping Jacks are a great way to strengthen your feet/calfs while getting some cardio in
Squats are a great way to strengthen your lower body (regular, forward, back, sides, holds)
High knees are a great way to "sprint" in place to get a sweat going and warm up. They're also tough on the feet at first.

lifting weights is a great way to target specific muscles, but body weight exercises and cardio can do worlds of wonders for your actual physical strength and ability. It's good to combine the two, because your stabilizing muscles and ligaments need to be strengthened as well. If all you do is bench-press, you may see yourself struggling to carry something compared to someone who engages his whole body (like a laborer).

Lastly, do it for yourself. Getting in shape feels great, even if that shape is only slightly better than it was before.
