Slacked off this summer, then Mrs. Z and I started hitting the gym again two months ago. Now we get up at 4:30 AM to go work out four days a week. Wasn't fun at first, now it's just okay.
I'll go legs-back-bi's on two days, chest, shoulders, tri's on the other two. No rest between movements. Moved to a high-rep (30 per set) approach and it seems to be working.
And I started bench-pressing again, after a 30-year hiatus. I'm only using - don't laugh too hard - 95 lbs. It's a start
However, no more cardio for now. My right hip failed on me this spring. Can still do leg extensions and curls, but no leg presses or full cardio. Planning on joint replacement maybe next spring.
