What type of exercise equipment should I get?

So I cancelled my gym membership, cutting costs. So I have been using a friends treadmill, walking round the,
dipper like some locals do, jump roping, a bit of yoga. But routine is not good for me.

I have a couple of options I have been considering. One of those exercise balls, which I had before, and my cat popped but I don’t have a cat anymore, I liked the workout but it seemed like the ball was too big and the smaller one was just a tad too small.

Medicine ball, which I used a bit at the gym for abs but don’t know how to use it.

There are skates I can get, but the times are limited for free skating at our one rink due to hockey practice and kids lessons and such.

There is also swimming, the most expensive of the options. And I don’t know how to swim being fearful of water. But I would like to overcome that and learn qs kayaking I flipped more then a couple times in more challenging water or when their was a lot of debris from flooding.

The other option is rebounding supposed to be really healthy for the immune system I learned about it over a year ago but had a gym membership and low ceilings, its an 80$ investment and I may move state after 4 months here. But I could always give it away or sell it.
