Our Performance #Fitness Endurance class not only kicks ass but it will literally kick your ass. #Repost carycrossfit with repostapp. ・・・ When do we go hard? How long do we go for? The answer is the same...#alldamnday. Our Endurance class is part of the #AthleticLab Performance Fitness membership. We do killer #running workouts incorporating body weight exercises, assaultairbike, kettlebells and concept2rowing. It's one of our more popular classes and members regularly compete together in road races, obstacle course races and even triathlons. One of our latest additions to the class is our use of polarglobal heart rate monitoring. #CrossFit #instafit #fitspo #running #endurance
