Abduction exercise1/7/2024 This is most commonly seen in women of younger age as well as older adults. 2017 Jun 4(4):50-53.Knee valgus refers to when the knees cave inward, making an inward curve appearance for the entire leg, giving a “knock-kneed” appearance.

Therefore, when training the adductor musculature, it makes sense to also add such exercises into a program to train in ranges of motions that may not be sufficiently addressed by more compound exercises. With this in mind, exercises developed to train the hip adductors directly – such as standing hip adductions with a band or cable, the Copenhagen hip adduction exercise, and the hip adductor machine – involve moving through larger ranges of motion of hip adduction than exercises like squats, single-leg squats, and lunges. Research demonstrates that strength gains are highly specific to the part of the movement one trains in, with limited transfer to the rest of the untrained ranges of the movement that may not be addressed in a given exercise (7,8). So, with respect to reaching greater levels of muscle activity in the adductors, isolation exercises are superior to squats and lunges.Īdditionally, it's important to see how the scientific evidence falls in line with the principle of specificity. However, the highest EMG values for the wide-stance squat (5), along with those found during a single-leg squat and a lunge, are relatively low compared to exercises that focus primarily on the hip adduction movement (6). Some trainers may want to argue that compound and single-leg exercises like wide-stance squats, lunges, and single-leg squats train the adductors effectively enough to offset the need for doing additional adductor isolation exercises. Here's how I perform the Copenhagen hip adduction exercise, which is a bit different than how it's commonly done. The Copenhagen hip adduction exercise has been shown to be a very effective movement (3,4) and it's one of my favorite exercises for targeting the hip adductors, along with the additional shoulder and torso musculature demands. (Since most are familiar with how to do the adduction machine, I've omitted it in the tutorial videos.) This is one reason why the programs I design include at least one of the following exercises each week: seated hip adduction machine, standing hip adduction, side lying hip adduction, and the Copenhagen hip adduction exercise. In other words, an emphasis on hip abduction exercises that's not complemented with performing hip adduction exercises may put you at an increased risk of injury. Now, although that specific strength ratio is based on one study, a 2015 systematic review found that hip adductor strength was one of the most common risk factors for groin injury in sport. And yes, they should be a weekly component of comprehensive lower-body program.īut research on professional hockey players found that they were 17 times more likely to sustain an adductor muscle strain (groin injury) if their adductor strength (muscles that move the leg toward the body's midline) was less than 80% of their abductor strength (muscles that move the leg away from the body's midline). Much has been written about hip abduction exercises like pushing your knees out against a band loop while you hip thrust or squat, lateral band walks, etc.
