Last few months all reps are 15-40. Fees great insane pumps.
Until I started working out with the Elite 3 bands I'd not heard of people doing 40 rep sets...well, which equipment it is just one set for each exercise. When I started working out with weights around 1960, the recommended number of sets and reps was 3X10 on every exercise. Over the last 60 years, I tried just about every routine ever published or suggested. What I've concluded is they all work....until you get bored with them. A couple of things that definitely changed as I've grown older is that I have to limit my total workout time for each session or I'm just going through the motions and it need more days of recovery thus each body part gets a direct workout twice a week.
The other day a neighbor came over to talk with my son-in-law. She is 89 years old, uses a cane and walks a minimum it 3 miles a day. Her late husband was also an avid walker. Unfortunately, awhile back while on a walk he tripped on a raised section of sidewalk, fell, broke his neck and died on the spot. I think it is pretty amazing his widow still continues her walks despite her age and how her husband died. I hope I'm still exercising 12 years from now.
