Strength Training on the Hammer Weight Machine
Hammer Strength weight machines were developed by Gary Jones after he left the company Nautilus, which also creates gym machines. Hammer Strength is now operated and owned by LifeFitness, a commercial gym equipment distributor.

Effects
-
Hammer Strength weight machines are plate loaded machines, as oppose to being pressure loaded as in other weight machines. Even though its plate loaded, Hammer Strength equipment is still considered a weight machine and not a free weight. This is due to the fact that Hammer Strength equipment still locks the user in a certain motion, and balancing the weight is not required.
Benefits
-
The Hammer Strength weight machine does not require the trainee to balance the weight, reducing the chance of injuries. Certain exercises, like the chest press, do not require a spotter. By taking the balance out of the movement, Hammer Strength weight machine allows the trainee to focus on the prime movers, as oppose to being limited by the stabilizing muscles during an exercise.
-
Disadvantages
-
Only focusing on increasing the strength in the prime movers can result in neglect of the stabilizing muscles. If the stabilizing muscles become significantly weaker, an injury in the prime movers can result. Strength built with machine weights often doesn't carry over to free weights, since the major muscle groups have become stronger while the stabilizers have not.
