I am 63 and was working out 4-5 times in the gym before the pandemic. At the beginning of COVID I had an extruded disk between L4-L5 and a month after that a knee replacement with complications. Finally was able to get back on a bike 5 months after surgery and felt like a jellyfish. During the pandemic my wife and I decided to work out at home 3-4 times a week with dumbbells, also push-ups and planks. 5-6 days a week as possible we row and cycle on alternate days. I might get back into more aggressive workouts at the gym but for now my routine fits my lifestyle and provides me with both strength and aerobic training with lower impacts. The key for me has been consistency.
