The pin-loaded selection dip/chin assisted chin pull-up machine is a versatile piece of equipment that allows users to perform both dip and chin-up exercises with assistance. This machine features a weight stack with a pin that can be adjusted to provide the desired level of assistance for the user. To perform dips on this machine, the user would grip the handles at the top of the machine and lower their body by bending their elbows until their upper arms are parallel to the ground. They would then push themselves back up to the starting position by extending their arms. To perform assisted chin-ups, the user would grip the handles at the bottom of the machine and pull themselves up until their chin is above the bar. The weight stack provides assistance to help the user complete the movement. This machine is ideal for beginners who may not have the strength to perform full bodyweight dips or chin-ups, as well as for more advanced users looking to increase their strength and endurance in these exercises. It is also a great tool for rehabilitation and injury prevention, as the adjustable assistance allows users to gradually build up their strength without risking injury.
