Body Pump this morning completely kicked my derriere! The class started late because the one before it overran, so the instructor decided to treat us all to what he likes to call 'splunges': a mix of shoulders and lunges because there wasn't time to do both tracks separately. Let's just say I don't think I'll be able to lift my arms tomorrow. Seems a lot harder to do shoulder presses and lateral raises when you're lunging at the same time!
