How much is too much? We're not talking about your dose of egg nog. We're referring to this end-of-year challenge! It's not long but if you factor in your holiday cheesecake and the fact that you will do a wall sit with one leg, this workout is clearly NOT meant for SLACKERS. Good luck...and if you can't finish, add a note about your stop time and 'save to calendar' so you can revisit in 2013! Cheers.
