Tip: Machine Laterals With Assisted Negatives

There are some great high intensity techniques you can use on medial delts that are safe and will lead to big time results.

For example, use heavy eccentric loads on a machine laterals. The proper way to do these is by doing the positive/concentric part of the exercise on your own, then have your training partner push down during the eccentric/negative part as you resist maximally.

I love these because unlike many negative protocols, they're safe to execute (most heavy negatives aren't), and they seem to really "dig down deep" into the medial delt muscle fibers.
