Hi all, I'm new to this forum and would first like to say hello. I love this from 'wezegan' so true. Exercise, especially weight training will increase your muscle mass as well as strengthen your skeletal structure. Strength training can increase bone density and reduce your risk of osteoporosis. Now, to gain muscle, you must also take in an appropriate amount of carbohydrates and protein. You can accomplish this by eating good, clean foods. If meal preparation is not convenient you can purchase protein powders but please read the labels, some contain things you may not wish to consume. As a last resort, you can also take weight gainer supplements, but please beware that these contain even more undesirable things. PS. Pure egg crystals and sweet potato and oat protein are now available as drink mixes. They are an alternative to the widely accepted whey proteins available. All are $$$, do your research carefully. Good luck and be well. Nice meeting you.
