The seat shove occurs when the drive of the legs is not well connected to the handle, this is usually due to poor posture or strong core which is the connection of the legs and arms.
Tell tale signs include;
• The seat moves independently of the handle
• The body angle closes as the legs are drive back
Tips for correction
• Focus on the seat being connected to the handle - the handle moves when the seat moves
• Focus on not closing the body angle but maintaining the same torso position through the beginning of the Drive
• Hold a strong core as you Drive with the legs
