I have been losing loads of weight since Christmas, just by eating sensibly, and working out at home every day with the free videos on YouTube. Even though I am nearly seventy and have had a knee replacement, I can still work up a full sweat every time, with practically no space and no equipment. I look for beginners, low impact and senior exercises. There are some terrific ones - even cardio -which can be done seated in a chair. I also avoid floor exercises, which I don't like. I like Walk at Home, which is easy for the uncoordinated, and also Hasfit and Jessica Smith and Fitness Blender. Injury need not stop you, Teetime!
