I have been doing an exercise which I came up with (not saying I invented it) that I have not seen before and I was wondering if there was a name for it.
Imagine the cherry picker move we used to do in school. Similar to that. This also reminds me of a diagonal sit-up.
Stand with your feet apart past shoulder width. Place a dumbell 5-10lbs at one foot. With the oposite hand, reach down and grab it. Using your lower back and abs, come back to a standing position keeping your back straight. The arm with the dumbell should track your leg (as if it were on a rail). The lower and repeat.
When I'm doing 3 sets of 10 (10 lbs) or 2 sets of 10 (25 lbs) I can feel I've worked out my love handle area (internal obliques?).
