Every time back day comes around, i feel like i cant isolate my back and work it out hard enough. If i stack on the weight, i feel like i lose focus and control and never really exhaust my back. If i drop the weight, i can really focus on back rather than my arms, and can get a solid burn around 10-15 reps. Im currently trying to bulk. I feel like my back, specifically my lats, are lagging pretty hard. What would you guys reccomend? Any advice would be appreciated. Thanks.
