What are some exercises I can do at 350 pounds
If you have access to a pool water exercises are great, but I know many of us don't have that option.
Youtube has a bunch of videos for seated exercises for people with limited mobility something like that might be an option. Resistance bands are a good choice also.
Any walking is better than none. If all you can do it to the end of the driveway and back at least you did something. When you build up your tolerance go a little further. Also look for some chair exercises on YouTube or TikTok. Resistance bands and light weights are great for muscle building, but you need to get in your cardio as well.
