I generally workout 4 days a week
Mon - back and bi
Tue - chest and tri
Thur - legs
My weekends free up during the cold months and I would like to add another workout. I am really interested in adding muscle. Would doing a day of Deads, bench, and squats on the weekend mess me up during the week? I do all 3 of these already in my existing workouts.
Any suggestions on what to do with my extra workout day would be appreciated
