Athletic performance in your 40s?
I’m well into my 40’s and have been able to completely overhaul my physical condition through diet, IF, (not 7 days a wk), lifting and conditioning. Very little in the way of exercise based cardio unless it is for fun, (skinning, hiking). I suppose I go for a short trail run from time to time.
Anyway, I am skiing better both up and down, hiking faster and farther without feeling exhausted as quick and participating in sports with my kids that I steered clear of a couple years ago in fear of hurting myself.
Things just hurt and ache more now.
