Alpha Max No2 A great technique for going around muscles that limit you during certain exercises is the pre-exhaust process. It is common for one frequently used muscle group to get exhausted before you work through all your exercises. Make use of an isolation exercise. For instance, straight-arm pulls downs will not put too much emphasis on the biceps. If you do so, this will make your lats very tired, and our biceps will work right.
