I had a great workout at the park. Crunches lying upside-down UPHILL (feet can’t touch the ground!), prone cobra raises lying facing downhill, sprints, push-ups, step-up lunges off the picnic table bench w/combined knee raises, side-hops, squats on those air balance disks while on a slope, on and on… in circuits… I only almost passed out once! Great job and thanks, Trainer Guy. Can’t wait to see how I feel tomorrow.
