Day 18 of #19erWorkout Challenge brings the half kneeling overhead press. Grab a weight and grasp with one arm at your shoulder height. Kneel onto one knee (half kneeling) on the same side as the weight. Keep your back erect and your chest out then push the weight overhead. Slowly lower to the starting position. Finish all reps on this side then switch. Repeat Days 1-17. Final push everyone, you're almost there.
