The bent press is a technical lift, and one in which you really don't "press" per say. It is more falling away from the weight and locking it out in the bottom. The exercise someone described above is actually a side press, there is a difference. Use light dumbbells and get the form down, but use something heavy enough that will make you work at the same time. If you are performing the kettlebell variety, use the 36 pound bell, if you use dumbbells, you should use something between 25-35 pounds (my guess anyway). The bent press is a fun lift, and great for core work among other things. I do them and I lift kettlebells a little as well. However, keep in mind while these are fantastic tools, they should not be the only things you do, in my opinion. I prefer building my workouts around the big barbell lifts and sprinkling in kettlebells and other things here and there. I think I read an article by Dave Tate a while back and he made reference to the forgotton exercises such as the bent press. He said they were forgotten for a reason. Something to ponder!
