I can't handle more than 3 days a week at the gym. I do my main lifts only once a week or I don't recover, but I am still getting stronger on my program. I have been lifting for more than a decade though.
I do cardio and lift on the same day, I also can't run every day or I don't feel great.
On off days, I just walk and do minor accessory stuff. Can't imagine lifting like this every day.
