Fellas im 41 and my metabolism as dramatically slowed down. I havent been eating that bad. I havent been eating that clean. I have the discipline to eat clean and stick to a good nutrition plan, but i have been surprised and a little discouraged how difficult it is become to lose weight and the lose of muscle. My knees are shot so running is out of the question but i will suffer through cardio if it is my road to salvation. I have been working out for a long time and i am familiar with nutrition and chemicals, im just wondering if there are any new suggestion out there that i can use to restart my comeback. Im certain my way may have gotten a little stale. I guess im really dealing with the lose of mobility some real sore joints and a slowing metabolism. Im getting older and i intend to fight it every step of the way. Any input would be appreciated.
