This is a great day to come in early and work on shoulder mobility. I would suggest the banded front rack, banded chest stretch, bar hang, and downward dog (2 mins each movement/side)
If finished, talk to a coach and work on a weakness for the remaining time.
With a workout like this you can make it easier or harder. If you have a decent base of strength make sure your trx rows are inverted. If you are doing renegade rows, try not to shift your hips, make sure your knees go to your chest on k2c, etc…
