I'm 46... Guide all fall in mountain terrain from sep to first of December before we get camps out. Then winter fun.Take 10" every morning and 15-20" each night to stretch, roll out stiff muscles and do flexibility/range of motion exercise....have been doing that for back and legs and it's worth the effort...water bottle or something that rolls to roll out muscles
100 Percent this is what makes the difference. Stretch stretch and stretch somemore
