This is a 30-minute upper body/core workout using a stability ball and dumbbells. Gunnar is with 4 background exercisers - 1 of whom shows easier modifications. He works back and chest, then does abs. Then goes to biceps/triceps and abs. And he finishes with shoulders and abs. The workout goes fast -- Gunnar demonstrates each move before the set, so if you are familiar with it you can add in extra reps.
He does some classic strength moves, with a functional fitness twist on them. The warmup is mostly stretches, as is the cooldown. The added twists keep it interesting, as does the ab/core work in between upper body.
I used 3, 5 and 8 lb weights, and got a nice intermediate workout, which is a good add-on to cardio or lower body work. I'm not a big fan of functional fitness type workouts, but I really enjoy the core secrets ---probably because they don't spen too much time on each muscle group.

Instructor Comments:
Gunnar gives good instruction, and is fun to work out with. He's not loud, and has a good sense of humor.
