This static stretch is a excellent way to open up the Chest while lengthening the Lats and Hip Flexors. A subtle but amazing stretch is not only great for movement prep prior to a workout, but is also beneficial for everyone, especially considering the hunched positions we frequently find ourselves in (think hunched over at a computer desk or curling up on the couch with your cell phone).
Try this stretch with or without a TRX Suspension Trainer. The advantage to using the TRX is the 3-dimensional movement it allows, where you can position your body along any plane for the optimal stretch of any muscle. Experiment with slight changes in position and weight shifts to get at hard-to-stretch areas.
As always, work within YOUR pain-free available range, and meet your body where it is.
