The iso-lateral chest press lets each arm work independently on separate handles. If your left chest is weaker than your right, this machine exposes and fixes that imbalance. You cannot cheat with your strong side—each arm carries its own weight.
When to use it
Use to address imbalances or vary training.
Who it's for
Lifters with noticeable chest imbalances. Those who want unilateral pressing options. Anyone using Hammer Strength equipment.
Watch for one arm moving faster than the other—that tells you which side is stronger. Focus on the weak side feeling the same effort as the strong side. Equal reps do not mean equal work if one side is coasting.
