4. Excessive endurance exercise
I am a 63 yo male in pretty decent shape. Except for a nagging hip injury I feel great. The hip doesn’t seem to have caused any loss in mobility or function (I can back squat 250lbs.). I consider myself to be Paleo since 2011 and recently have thrown in some keto and intermittent fasting. I’m wondering because of the hip and my age if I should be lifting crazy heavy (going for new PBs and competing at local CrossFit gyms) or should I be lifting lighter (and safer?) with more reps?
Do you have any guidelines for people “wiser” than 60?
