Directions
Lying with your head just off the edge of a bench, grab a kettlebell or matching weights. Bring the weights up and your knees at 90 degrees. Flatten your back to the mat, then keeping your elbows stationary with a tight core, while letting the weight go down as you legs go to straight out. Keep core pressure into the bench as you breathe out at the bottom of the rep. Take care to get a full range of motion with the dumbbells with locked elbows.
