I'm having a few issues working out my back. I've been doing weightlifting on and off for about 4-5 years and this has definitely been a problem for much of the time although I have recently started training hard again after a 4 month break and it seems to be worse than ever (I have been working out again for 2 months, 3 days a week).
My back workout consists of a mixture of four of the following followed by two bicep/forearm isolation exercises:
Machine equivalents of the above
Generally on the third exercise I find my forearms and biceps are giving way even though my back can easily continue, and on the fourth exercise it becomes a real problem. For example, my forearms get so weak I have trouble maintaining grip. I always leave bicep/forearm isolation till the end so I'm not sure how about to fix this other than concentrating more on strengthening forearms/biceps before trying more for back.
Does/Has anyone else had this kind of issue? How did you get around it? Any advice to offer?
