For me, I have always hit the gym. I have had a solid routine for years but got comfortable. Now I am pushing it more with lifting. Told myself for years that I was “too old to dead lift”… Well that is not the case. Mind you I am not doing crazy weight, but I am lifting to failure in reps. I have built up to 225lbs and today I did 12 the first set, 9 the second, and 7 the third set then dropped down to. 135 and did 20. Disclaimer, I’m 5’6 and weight 152lbs now.
