I'm 40 years old.
Been using steroids and lifting heavy since I was a very young teenager.
Over the last (approximately) 10 years, I have done less and less lifting and more heavy bag, speed bag, medicine ball slams and a variety of functional exercises.
For roughly 6 months now, I have done literally zero weight lifting (actually played around on the bench the other day with super high reps but other than this I have done no lifting at all).
My workouts are now exclusively a variety of boxing and bag exercises along with battling ropes, sledgehammers, medicine ball throws and grappling dummy throws.
Also quite a bit of mitt work.
Additionally, I do some jogging and some 40 yard sprints along with some traditional cardio like the stair climber and the arch machine.
Now granted, I have a great deal of muscle mass from all those years of food, drugs and lifting but I can honestly say that I have never felt better in my life.
I definitely have a leaner and more athletic look than I did previously. My wife seems to be digging this.
Also, all those old aches and pains are gone. Thank God.
