Background: Albuterol is a beta-2 agonist that has been demonstrated to increase muscle strength in studies in animals and humans. Based on a pilot study of extended-release albuterol Repetabs in children with dystrophinopathies, the authors conducted a randomized, double-blind...

CORE STRENGTH . 📚 The core is not only the rectus abdominis and oblique muscles, but rather muscles that attach to the hip that aid in stability. These isometric variations do not change length during the contraction, but still produce force in the muscle. This can aid in more postural and...

𝐏𝐀𝐓𝐄𝐋𝐋𝐀𝐑 𝐓𝐄𝐍𝐃𝐎𝐍 𝐑𝐄𝐇𝐀𝐁 . . . 💥 Patellar tendon issues? Achy knee? Right in the front? Well here is how you can begin the process of strengthening the tendon and surrounding structures to help it adapt! Isometrics are commonly used initially for tendons which is when a muscle is being contracted...

Lifters often forego isometric training as they feel it won’t have much impact on hypertrophy. While that may have some truth to it, isometric training is incredibly beneficial for joint health. This study found that isometric training significantly increased patella tendon stiffness compared to...

Biomechanical analysis of elite powerlifters showed that these athletes produced significantly less force in the starting position compared to other positions of the deadlift. Train exercises like deficit deadlifts and speed deadlifts to improve your strength and power off the floor to overcome...

I've never understood why bodybuilders apply 21's only to their biceps. The way I see it, 21's are a simple and versatile overload technique that can easily be applied to almost any strength exercise. As a refresher, 21's are usually performed by doing 7 partial reps at the top of the range of...

by Jake Tuura We know that swearing increases pain tolerance. That has even been backed up by research. Now new research shows it can also increase strength and power. . The Studies: Repeating a swear word was compared to repeating a neutral word during two different experiments. In the first...

For years I was frustrated with my deadlift. I came out of the gate very fast, deadlifting 675 at 220 in my second meet. But from that point in 2002 until 2014, I was stuck between 675 and 710. Finally, after some knee problems that lead to surgery, I was able to make some progress. This was the...
