Sure, why not. I've been working out most days (have missed a few days here and there). I do push ups, planks, various other stuff, and free weights. Also walking. I keep my diet clean (that is whole grains, veggies, fruit, olive oil and extra virgin coconut oil, lean proteins, and minimum on the sugars). Pretty much been doing this since March this year. (Actually earlier but I had top surgery and took a long hiatus.)
I'm not trying to get huge muscles at my age, as I think it's dubious, but trying to keep tone and have gotten some baby pecs. So I am more working with lighter weights (8 lbs) and more repetitions.
I lost a little weight earlier, but I don't really need to lose weight anymore.
