I had one of my Online Personal Training Clients mention that they where starting to get up in weight in their dumbbell bench press and where concerned about getting the extra weight load into position since they have issues with their back and did not want to potentially potentially strain or injure their back.
As with everything everything there are easy ways and hard ways to go about doing things, if you use technique rather than muscle to maneuver yourself into position when doing a heavy dumbbell bench press, then the amount of weight you use should not be a problem or put any unnecessary strain on your back.
In this YouTube video I show you how I use my legs and upper body to work with each other as counterbalances and get pretty much as much weight as you can handle when doing dumbbell bench press.
