That’s a problem. “Elongated periods of sitting sends messages to certain muscles to stay turned on, which keeps other muscles turned off,” says Beachbody fitness expert Cody Braun. “This creates an imbalance, which can immobilize your hips.” Your hips are built to move in almost any direction, explains Braun, and when they’re stiff, they don’t just make exercise more difficult; they also make you more prone to pain in surrounding joints — including the oft-troublesome lower back.
Stretching is your next move, but not just any stretches. "Before your workout, you want to go for dynamic stretches, or stretches that put the joint through a full range of motion," says Lefkowith. Moves like squats and lunges will get your muscles fired up (especially if you focus on squeezing your butt at the top of those squats), says Lefkowith.
Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
