Swing it for an xtra tug!
I thought I’d offer up alittle technique I use while hanging that I think could help provide some extra stretch.
Sometimes I will swing the weight between my legs. Not a wide swing, only about 24” between each end. Possibly not a good idea with heavy weights. I only use about 5-8 lbs., but it gives a good gentle tug on the down-swing.
You can also swing side-to-side for a different stretch. To hit your ligs at a different angle higher up on the lot, just bend over and place your hands on your knees for support. I will swing for 3-5 mins. and feel a pretty good stretch afterward.
