Hi.I'm 64 and would like some advise on getting fitter.I'm 6' and about 160 lbs,I lost 20-30 lbs over the past months due to stress(divorce).I've been working out with dumbbells for the past 5 months,currently doing rows,triceps press alternating every other workout with overhead press curls 8X5 and pushups(to failure)s three days a week,squats 6x6 and running or sprinting three days a week on leg day.I'd like to do more.my diet is terrible,i don't eat enough,stress again.I'm trying to focus getting more protein and less carbs and fats.My testosterone is good.I'd like to gain more muscle which i understand is harder to do at 64.I'm fairly lean but still have some fat.I want to be healthy and live as long as possible.I do take vitamins.I'd prefer not joining a gym,as least yet.I'd like to incorporate other pieces of equipment than just dumbbells.thanks for the help as always.
