The Straight-Arm Pull

Spotting the Straight-Arm Pull, Pull-Up, and Alternating Grip Pull-Up

9-42. The front spotter assumes a staggered stance with the palms toward the exerciser at approximately chest level. The front spotter’s primary role is to support the exerciser if their grip fails. The rear spotter assumes a staggered stance and holds the Soldiers feet on their thighs or abdomen. The hands are placed above the ankles to hold them securely. The role of the rear spotter is to provide a stable base for the exerciser to push against with his legs. When spotting is performed correctly, the rear spotter will neither have to lift nor go up and down with the exerciser. The rear spotter must anticipate the last repetition and release the Soldier when the “down” command is given before the “dismount” command. Soldiers are required to use the foot pegs when mounting and dismounting the bar. This is done to ensure safety and to reduce injuries. Jumping from the mounted position causes compression to the spine and other joints of the body, possibly resulting in injury.

EXERCUSE 1: STRAIGHT-ARM PULL
Purpose: This exercise develops the ability to initiate the pull-up motion and maintain a contraction in the extended hang position (Figure 9-24).

Starting Position: Extended hang using the overhand grip.
Cadence: MODERATE

Count:
1. Keeping the arms straight, pull the body upward using the shoulders and upper back muscles only.

STRENGTH TRAINING MACHINE DRILL


STRENGTH TRAINING MACHINE DRILL
EXERCISE 9: TRICEPS EXTENSION

Purpose: This exercise develops strength in the triceps muscles (Figure 6-44).

Starting Position (Standing): Straddle stance with a 90-degree angle formed at the upper and lower arms. Select the appropriate weight and ensure the pin is secure in the weight stack. Maintain an erect position, eyes
looking straight ahead, grasping the bar with a closed, pronated grip.

Starting Position (Seated): Seated position with the feet firmly on the ground. The seat is adjusted so a 90-degree angle is formed between the upper and lower arms, with elbows shoulder-width apart on the supporting
pad, with hands in a closed-grip. The hips and low back are firmly against the seat back with the eyes looking straight ahead. A natural arch is maintained in the lower back. Select the appropriate weight and ensure the pin is secure in the weight stack.

Cadence: SLOW

Count:
1. Push downward until both arms are fully extended, but not locked.
2. Return to the starting position.

Check Points:
􀁺 Feet remain on the ground, with hips and back firmly on the bench during seated triceps extension.
􀁺 Keep the head and neck in a neutral position, looking straight ahead.
􀁺 Exhale on count 1 and inhale on count 2.

Precautions: Do not lean forward while performing standing triceps extension. Do not arch the back or allow
the hips to rise off the bench during seated exercise.
