If you have hit a plateau or you're looking for a way to increase the intensity of your workouts, partial reps are the way to go.

During my bodybuilding prep I utilized partial reps to get that extra pump thats so hard to achieve during dieting. (The pump refers to the swollen feeling your muscles get while training. The nutrients and water in your system can help or hinder your quest for the pump. That swelling effect is due to the increase in cell volume and is essential for muscle growth.)

Execution: I like to think of my reps are divided into 3 sections. Top, middle, bottom. Partials are typically executed by moving the weight through the middle portion of the movement. Although you can execute your reps in the bottom or top of sections of the movement. 

Partials can allow you to use more weight since you're not going through the full range of motion or as a finisher to your sets when full range of motion is not possible anymore.

Or maybe you struggle with the 1st pull of your deadlift. Simply execute multiple set of partials in that range of motion or add it as a finisher at the end.

They can be very demanding so be sure to take a break from them every 3-4 weeks.

Let me know when you use this training principle and how it worked for you!
