Diet change is probably the most important for weight loss. But for getting into a routine of exercising my weird tip would be: Get yourself an Meta Quest 2 and install Thrill of the Fight, Pistol Whip, probably Beat Saber. If you're like me and you dislike the monotony of "normal" cardio exercise, this will make it easy to get your daily dose. Somehow the immersion and gamification allow me to push myself harder than I could ever do just by force of will.
The first time i saw Beat Saber i was pretty convinced this would be the ultimate weight loss game for me. Unfortunately a VR device it's way too expensive for me at the moment.
Yeah they're pretty expensive. But I guess gym memberships can be too. Of course there are great free ways to exercise at home. This machine is just a massive boost to my motivation to actually do it.
Seems like an interesting project would be to hack in an audio sensor to a Beats style game so that you can whack targets with a large cardboard tube and have those register as hits.
