Use school bags
One of the most underrated items at home to work out with are school bags. Not many people can see the beauty in using school bags to work out, but should you put your mind to it, things could work out for you rather well.
Now the idea is to use the bags by putting a lot of books in it to create more weight. Once this weight is created you can use the backpack to run with, do push-up with and any other thing that requires weight resistance of any sort.
Buckets of water
Another option that you have at home is to use big buckets of water to work out and work on specific areas.
Now these big buckets of water with their handles can act as really big dumbbells, as long as you are able to balance them properly while lifting them.
At the same time, you can adjust the amount of water in them, which in turn would adjust the weight.
However, you can also put other items in the buckets as opposed to water if you don’t want to create a mess.
In order to work on your back and wings, you may need to find any ledges or any part in your house where you can hang from. Now once you hang from there, go ahead and use it to do pull-ups and other exercises that require you to go against gravity and pull yourself up.
If possible you can also get your legs to stick in there and then do vertical abdominal crunches.
