The quadriceps are four muscles located on the front of the thigh that allow for straightening of the knee and leg extension. The rectus femoris also acts as a hip flexor. Strengthening exercises, such as straight leg raises and machine exercises, can prevent injury and support the knee joint. Proper form and consulting a doctor before starting a new exercise routine are important.
Located on the front or front of your thigh, your quadriceps are made up of four muscles. These muscles are called the vastus medialis, vastus intermedius, vastus lateralis, and rectus femoris. Attached to the anterior portion of the tibia, most of the quadriceps muscles start at the top portion of the femur. However, the rectus femoris starts at the pelvis and extends through the hip joint.
The quadriceps work to allow for straightening of the knee and extension of the leg. Like the other quadriceps muscles, the rectus femoris helps extend the knee. However, it also acts as a hip flexor.
It’s important to keep your quadriceps strong to allow for the greatest level of flexibility and to prevent injury. There are exercises and stretches to help keep your quads strong and flexible. Taking care of your quads not only helps protect you from muscle injury, but it can also help support your knee joint and protect it from injury. Such exercises can be found on the Internet, as well as in fitness magazines and books. Keep in mind, however, that it’s always a good idea to check with your doctor before starting a new exercise or stretching program.
Straight leg raises are good for encouraging strong quadriceps. To perform a leg raise, lie on the floor with your legs straight out in front. Then, bend one of your knees to a 90-degree angle; keep the foot of that leg flat on the floor. Keeping the other leg straight, flex the foot and slowly lift the straight leg until it’s six inches off the floor. Hold it in that position for a few seconds, then slowly lower it to the ground. Repeat ten times before switching to the other leg.
Many quadriceps exercises are also useful for strengthening the hip flexors. Make sure you focus on contracting your quadriceps as you perform the exercises. Also, it’s best to start slowly with any new exercise routine. Exercising too fast and too hard can lead to injury.
You can also use exercise machines to train and strengthen your quadriceps. Among the best exercises you can do with a machine are leg extensions, lying squats, hack squats, leg presses, and thigh abductors. To get the most benefit from these and other machine exercises, be sure to pay attention to proper form. Proper form is also important to prevent injuries.
