*Ouch* coming back from taking time off is always tough. Modifying exercises and allowing your body to ease back into your workouts is always the best course of actions. Have some patience with yourself and you'll be back where you left off in no time.
I love using the springs to "help" when it's needed as opposed to making things harder. Facing the opposite direction allows the spring to help you roll up into a teaser position. Great for stretching the lumbar spine too!
