I have 5 minutes to decide....

Should I do weights on my legs this morning, and then return tonight to do arms?  I am trying to fit in weight training into my routine, but have a hard time doing it.  I have to opportunity to hit the gym this am for an hour; is it o.k. to do two weight routines in one day? 

As long as it's different muscle groups, yes.

Full body is just as good (if not better) than a split routine, and you aren't doing anything different by splitting them by <12 hrs. Do a full body.

Thanks!

imo, do full body.

i was at the gym for just over an hour this morning and managed a full body.

i am sure you can did it all in an hour.
