Going to the gym, you may not be able to stick to it at home, and there is no effective plan. Running can exercise the muscles of the whole body, just jogging, and then doing some kicking and squatting. Exercise your legs. Lie flat on the mat, step on the mat with your legs bent 90 degrees, tighten your abdomen, relax your shoulders, and lift your upper body with the strength of your abdomen. 30 degrees is enough. Do it 8 to 12 times, take a break and do 3 to 4 groups. Remember to relax when you are finished. Lie on the mat to support the upper body. I hope it works for you.
