I have noticed that the older I have gotten the slower I recover. I am in my early 40s.
Don't you just hate this?
I've found that eating for recovery after any long workout or strenuous day is critical. I'm 51.5. The guidelines i follow are to have some carbohydrate and protein within 30 minutes post workout, and then to make sure I get another meal or mini-meal about two hours later, focusing on complex carbs and lean protein. For post workout, sometimes I opt for a bottle of Recoverite by Hammer, and sometimes I do it with something an orange and Mrs. Mays nut bar. This is really critical on the hard days.... we (DH and I) started really paying attention to recovery eating because we were having
"exercise hangover" issues after a hard day of all day mountain biking or powder skiing. It's helped immensely.
