What is the correct spotting technique for the barbell lunge?

Keeping hands 'close to' (without constant contact) the hips/waist/torso allows the spotter to be in position to assist if balance is lost while avoiding unnecessary interference with the client's movement pattern and proprioceptive feedback. This technique balances safety with allowing the client to perform the movement independently.

Keeping hands near the barbell places the spotter in a poor biomechanical position and does not allow effective control of the client's center of mass during a lunge.

Placing arms underneath the client's arms restricts the client's natural arm movement and balance adjustments, which are critical for lunge stability.

Keeping hands on the client at all times disrupts proprioceptive feedback and alters the movement pattern, making this less appropriate than a 'hands close but not touching' approach.
