HOW: Start in a long sitting position holding weights in each hand in front of your shoulders. Begin the exercise by keeping the rest of your body still and performing an overhead press. Hold the overhead position for a moment (the weights should be in line with your ears), slowly lower the weights down and return to the starting position and repeat.
FEEL: This should feel like an upper body workout, specifically your deltoids, traps, triceps, and upper back muscles. You should feel your shoulder blades working a lot with this exercise. You may also feel your abs and lower body working a bit to maintain optimal long sitting posture.
COMPENSATION: Do not excessively arch or bend your low back. Keep the rest of your body still as best as you can. Do not use momentum to move the weights, also focus on moving slowly, maintaining time under tension. Avoid excessive shrugging.
