Been casually lifting for over 30 years----your videos have pointed me in new directions and led to almost immediate visible results. Great stuff, thanks.

Love the break down of the smaller muscles as well as the main biceps!

Please keep posting more videos.They are helping me greatly understanding my body and I am applying it to the workouts.Thanks James..You are the real deal.Much respect!

I was reacquainted with reverse curls and arm focused pull ups after watching this. The pain the next day was intense. Thanks for the reminder!

James I have to tell you I have always felt so lost in the gym no matter how much I read about working out. I'm a bit of a science geek but have always wanted to be strong and fit. I've watched several of your videos now and I really appreciate them. The combination of information and how to use it in the gym is amazingly helpful. It appeals to both my inner nerd and athlete. Thank you. I hope to emulate your example. Keep up the great work and take care man.

i appreciate this specific type of videos plz plz dont stop making this ones i love the humorous parts too

the 2016 new guy who really knows what he's talking about. thumbs up Mister Grage

dude you rule please keep this shit up!

dude im so glad I found your page, thank you for your very informative videos

Best online trainer ever!!!

Wish I had more thumbs! This is the most valuable information I’ve ever watched... down and dirty with dumbed down explanations! I swear by your videos and have turned tons of my military colleagues onto this series. Many of them tell me they wish they’d seen this years ago before the injuries and the time wasted in the gym just “doing what everyone else does”.

Love the videos! They're so informative, especially when you're breaking down the muscle fibers for specific details. Please keep the info coming, you have significantly improved my training.

man I've really been trying to figure out exercises to build my biceps higher and I thank you for supplying us with the knowledge of how to do so! you really break down the exercises to benefit people that need help once again thank you!

Love how in-depth your video is. It is really hard to find videos on the science for what to work and why. Thanks for the awesome video.

This really is one of the best, most informative fitness channels on YT.

talking about how the muscles works and showing how to the the exercise is very important i will try it on my next bicep day.... thank you and please continue to make videos

Great explanation of how brachial work and how it can make upper arms look thicker

This video is great. Definitely going to watch more of your videos because not only do you show how to workout the muscle you explain why.

Your channel is literally a gold mine, Mr. Grage. I'm loving the series with Kirby aswell, can't wait to see him add some size! Already loving how his form progresses and your work on him. Keep it up.

Thank you for posting this. As a female bodybuilder, I am intrigued in learning the mechanics in order to target all of my muscle groups. I appreciate it.

Fantastic work mate love the vids

Agreed! In order for me to first fire my brachialis I had to start light and over a few weeks I began to move up in weight. Starting light really gave me that mind muscle connection and now I can lift heavier while being able to engage my brachialis.

Thank you for sharing your knowledge!
