This week’s challenge was popular! It was called Bocce Bell the goal was to roll a 4 pound ball and try to hit the far kettlebell that’s 30 feet away and would be worth 25 points. The kettlebell in the middle of the ladder was worth 15 points and each square had its own points too. Everyone had 2 warm up rolls then the next 3 would count. The SportsPlus staff almost swept the medal stand but Eliot and Taylor had to get in the way!
