Maybe some 3kg -5kg dumbbells and a mat/rug to start with? If you like the first few, you might eventually need a resistance band and a yoga block/something to elevate your heels.
You can definitely do it, if it's hard at first bear with it as you'll see results in your endurance. I was 5 stone overweight when I started a year ago, and now I'm a healthy weight. Mainly due to diet but strength training has changed my body more than any other exercise I've ever done.
