Using The GymBoss Interval Timer for GPP/Conditioning Part II!
Per my video of my current GPP/Conditioning day using the GymBoss Interval Timer, which was fun to make, not so much fun to follow, I have made another with Kelly D! I’m no cross training/endurance God I can assure you, and brief, intense workouts like this are how I prefer to get in my conditioning workouts. As you will see, Kelly is in great condition, and now no women out there have any excuses not to try this workout! 
I recommend an interval timer like the GymBoss, but one could do it (less efficiently I might add..) with a stop watch. Enjoy!
