Nemeo’s take

This exercise is excellent for targeting the lower portion of the pectorals with marked tension in the stretching position, but the unilateral aspect imposes a strong demand on the core and can limit the load due to stability. Compared to the classic decline press with a bar, the isolation is better but the progression in load quickly becomes limited by the balance. Ideal if you are looking to compensate for imbalances, but not optimal for maximizing progressive overload in the long term.
