Here are some fun things you can do to work on your arm strength and shoulder flexibility.
Place a loop around your wrists behind your back. Press out into the strap to broaden across your chest and bring your shoulder blades into your back. This will also help to straighten your elbows.
Anne Schultz who I think learned it from Laurie Blakeney. Place a looped strap lower down on your arms, so the strap presses against the bottom of your skull. This will open up your shoulders quite a bit. You can tighten the belt enough to get your hands together in Urdhva Namaskar, if your shoulders will allow it.
Please don't eat the straps.
