The results illustrated that during high-strength clenching (≥50% MVC), antagonist muscles are activated simultaneously to increase muscle strength. High-strength clenching improved kinetic performance (joint fixation), whereas low-strength clenching (<50% MVC) enhanced exercise performance (joint movement).
Flexing your muscles isn't just about looking good; it can also boost your mental and physical health by treating headaches, high blood pressure, digestive problems, and more.
By squeezing your muscles and applying maximum tension to each muscle contraction and repetition, you can catapult out of your plateau to new heights. So how do you do this? One of the most important contributors to muscular growth is the tension that muscle fibers experience under load.
Tensing painful muscles can reduce pain. This is how. Research has shown that these contractions can be very strong, with less pain and less inflammation. Hence why they find themselves into many of our patient rehabilitation programmes.
It may very well be the main cause of your tiredness, your many aches and pains, and speculatively even your high blood pressure.

Habitually contracting your oblique abdominal muscles can exert force down on the pelvic floor muscles and potentially cause the pelvic floor to become overwhelmed, which could have consequences such as incontinence and pelvic organ prolapse, said Jeffcoat, president-elect of the Academy of Pelvic Health Physical ...
The easiest option is to flex and squeeze your body. From your glutes and your abs to your pecs and thighs, you can get rid of a few calories by simply flexing them as you work. As you grow accustomed to the flexing, you may find it to be a great way to work your way through a long, difficult meeting.
Muscle relaxation, squeezing and relaxing each muscle of your body from head to toe, can help reduce feelings of anxiety, worry, anger and pain. It can also help you sleep better.
While they might not give you totally chiseled abs, abdominal-tightening exercises are a great way to improve your muscle tone when you're otherwise sedentary. They're also a good way to ease into ab work when you're recovering from an injury or after a surgery.
Subjects who were told to “squeeze the muscle”—an internal focus of attention—there was a 12 percent increase in the size of the biceps. That was almost double the gains seen in the group who were told to “get the weight up,” where the average increase in biceps size was just 7 percent.
“Once the lift is complete, and you release the muscle contraction, your blood pressure drops dramatically, which sometimes causes people to become lightheaded or even pass out before the pressure can normalize,” he stated.
A tight core improves every fitness movement. For cardio, your stability, oxygenation, and endurance will improve. In lifting, it means you're stacked: all your musculature is working together, allowing you to lift more.
Stress and anxiety.
People who often feel stressed and anxious may be more likely to get trigger points in their muscles. One theory is that these people may be more likely to clench their muscles. Clenching is a form of repeated strain that leaves muscles open to trigger points.
Clenching offers fantastic benefits; the best being that it strengthens the tendon, the tissue at the ends of each muscle that attaches the muscle to the bone. This of course increases the strength of the joint. In fact, when you clench a muscle, you'll actually feel it in the tendon.
Unfortunately, sit-ups and crunches can't eliminate visceral fat directly. You can't reduce fat from specific parts of your body by exercising that body part; our bodies simply don't work that way. With sit-ups or other abdominal exercises, you're toning the abdominal muscles but not burning intra-abdominal fat.
While there isn't much research on the long-term strength adaptations of flexing, there's loads of scientific evidence that concentric and isometric contraction are good options for building strength and size (1). In other words: by simply flexing any muscle, you can build it.
What is hourglass syndrome? Hourglass syndrome is a disorder in which people suck in their abdomen habitually. There is an activation of the upper abdominal muscles because of the pulling of the diaphragm toward the opposite direction that inflates the lungs.
Butt-clenching involves the action of tightening then releasing the glutes and while it won't give you the shape and firmness that comes with regular lunges and squats, it will help strengthen your glutes which will help maximize those lunges once you get to them.
It's the movement that's implied when your coach, fitness instructor, or physical therapist tells you to tighten your core or brace your abs. This motion comes into play in a lot of exercises because your lower back is more stable when your core muscles are braced.
