I own almost every piece of fitness equipment they sell and take their supplements every single day. I highly recommend Onnit products for anyone who wants to move better, train harder, and feel amazing.

Jim Smith Recommends
Buy Shroom Tech® SPORT
I can honestly say that Shroom TECH™ Sport is one of the most effective supplements I have ever used. I can immediately tell the difference when I don't take it. We incorporate a ton of high volume strength training and heavy conditioning work in our program and, when when my athletes and I use Shroom TECH™ Sport, we can go longer and get more quality reps because it pushes the lactic acid threshold to later in the set.
Buy Warrior Bar
Because I am always on the road traveling to our certifications, to the gym, and seminars, I am always looking for good snacks that I can grab on the run. I love Onnit's Warrior Bars and Oatmega bars because they are super convenient and actually good for you. They taste freaking amazing!
Buy Shroom Tech® IMMUNE
I have been in the weight room for 30 years. Onnit took my recovery to a whole new level with Shroom Tech® IMMUNE by combining turmeric and ginger root. It’s a must-have for all lifters, coaches, AND athletes because your ability to train hard is directly related to how well you recover.
