Hello all. So, is there a way for a 40 year old body to be able to still build muscle needed to compete in cycling? Yes, I'm 40 and just came back to cycling after about a 5 year break with no cycling at all. From what I understand is that the body begins to degrate (for search of better words) once it stems into its 40's. Is there a way for me to be able to train and build the muscle needed to compete once again?

Do you people find it better to obtain more carbs or more protein? I'm currently at 155lbs. and a lanky 6'1". Any input and advice will be appreciated.
