Machine of the Month - D5 Arm Cross Machine
The D5, or arm cross, isolates and strengthens the pectoral muscles of the chest.
This machine is a great addition to a training program as the pectoral muscles, or pecs, provide stability for the shoulders and the body’s skeletal structure. Having a strong upper body helps in a number of everyday movements, such as, pushing yourself up from the floor or bed, pushing open a door or moving a heavy object.
Important Technique Points
- Ensure that the pressure is exerted from your elbows and lower arms, not your wrists or hands
- When at full contraction (elbows together), make sure your shoulders aren't protracting (pushing forwards) as this can cause neck tension
- Be sure to keep your back fully on the backrest to avoid arching your back. This ensures you are isolating the targeted muscle group
- While performing the exercise, ensure that you do not open your arms more than 180 degrees to avoid over stretching the shoulder joint
