Is it a no no to do the two gym style upper body work outs on back to back days? What about on the same day, in the same work out?
I do both of the GS uppers on the same day - it's long, but I like to do upper one day and lower another day. If I separate the uppers, then it takes up a third day.
I always separate them because I run every day too. I try to keep my workout DVD an hour or less because I add 30 to 45 more minutes with the running. That's enough for one day!
