A neutral grip would be thumbs up.

A neutral grip is characterized by the palms facing each other, which often places the thumbs in an upward position—often referred to as "thumbs up." This grip is commonly used in exercises such as dumbbell lateral raises or machine shoulder presses where joint stability and shoulder alignment are prioritized.

In contrast to overhand (pronated) or underhand (supinated) grips, the neutral grip can reduce strain on the wrists and make movements more comfortable for individuals with certain joint issues. The “thumbs up” orientation of the hands in this grip also allows for a strong and safe position during various resistance exercises.

Understanding the characteristics of different grips is essential for personal trainers to prescribe the right exercises safely and effectively.
