I would add aerobic exercise to all of these great lists. Think of activity that raises your heart rate and breathing, but less strenuous than a cardio workout. An elliptical on low setting. Prolonged periods of slightly faster than a walk. It could be labor, exercise, playing, or walking your dog quickly. Realize that if the person is in bad shape we don't want to bring on a heart attack so start out slow and stay slow for months until the heart strengthens and the arteries hopefully regain elasticity to accommodate the pump. https://en.wikipedia.org/wiki/Aerobic_exercise Sedentary lifestyle is the worst for us along with the carbs, sugars, and preservatives. FDA, food producers, and jews rend poison out of worthless byproducts and convince you to pay them for their soy cottonseed oils. Then we pay a dothead at the mayo clinic for Pfizer prescriptions and food pyramid diet plans.
