Training and nutrition advice
Something a lot of us are taught is to perform exercises/lifts through a full range of motion. When you bench press you touch the bar to your chest, and push all the way back up. When you squat, squat as deep as you safely can (definitely below parallel for the most leg development) and stand all the way back up.
Some people advocate partial reps. I did this with a client looking to add muscle mass through body weight training. He was too strong for certain moves and had a lot of really really high reps, especially the squats.
I had him do various partial range of motion reps to pre-exhaust his muscles, essentially making his own weight much heavier when he hit the full range of motion. So, there are certainly times when partial range is beneficial. However, most of the time, it's probably best for all of us to be working in a full range of motion.
There is a FANTASTIC video presented by Juggernaut Training Systems where Dr. Mike Israetel explains the benefits of full range of motion lifting, and what happens with our bodies during the lifts.
Here's a simple breakdown of what Dr. Israetel discusses in the video posted at the end of this blog entry:
That's basically the video in a nutshell. Definitely worth your time to watch this:
