The 'heel hook' is a type of knee lock used in some forms of martial arts to stress the knee and cause opponent to concede defeat. While the knee is in a flexed and valgus disposition, an internal rotation force is applied to the tibia. Reports are lacking on serious knee trauma as a result of this technique.
tl;dr. Hanging knee raises are a bodyweight exercise that targets your central core and lower abs. You do them by lifting and lowering your knees while hanging on a pull-up bar. Hanging knee raises require great upper-body strength. You can modify the move by doing it while lying down.
About the hook lying
This exercise involves lying on your back with your knees bent and feet flat on the floor. Your arms are then extended behind your head and you lift your shoulders off the ground, reaching towards your feet.
Elevating the affected leg can help reduce blood flow to the knee, helping to alleviate inflammation, swelling, and discomfort. Ideally, the affected leg should be elevated above the heart. To do this, lie down with the knee and calf propped up on pillows.
The leg raise is a more advanced progression from knee raises since the lifter must raise the entire weight of the leg (instead of the upper thigh only), making this movement more demanding on the abdominal muscles and lifter's ability to control their core and movement.
In terms of volume, the lying leg raise may be performed with far more repetitions than the hanging leg raise – both due to grip strength no longer being a limiting factor and the fact that the lying leg raise is comparably easier to perform, both in terms of muscular strength and in exercise complexity.
Knees should be “soft” and not locked. Locking your knees forces the pelvis and chest to be pushed out, which causes undo stress on the lower back. It is also difficult to maintain proper balance in an unnatural posture.
Hanging Knee Raises Workout
Beginners should perform between 6-8 reps, for 4 sets, 3 times a week. Intermediate level athletes should perform between 9-19 reps, for 4 sets, 3 times a week. Advanced level athletes should perform 20+ reps or more for 4 sets, 3 times a week.
Straight leg raises improve the strength in your quadriceps, which can support knee health, even if you currently have knee pain.
Straight leg raises increase knee muscle strength and protect the knee without including the knee joint while mini-squats strengthen knee muscles by including the knee joint.
In addition to using the abs, hanging leg raises rely heavily on the serratus anterior for stability, which has a huge effect on the entire abdominal region. You'll also get additional grip, arm, and shoulder work just by hanging from the bar. Sadly they're also one of the most commonly butchered exercises.
Leg raises are great for your abs and the obliques. It helps in building stronger abs, increase stability and strength, melt belly fat and tone your body. Leg raises completely isolates the rectus abdominis muscle which helps in toning your stomach.

They are “an Athlete Method favourite” for good reason then, “because as well as working your lower abs, leg raises also improve the strength and flexibility of your hips and lower back.” However, leg raises are most beneficial when you perform them slowly.
These muscles tend to be tight, contracted and under used since we are sitting down so much. Even when we walk, we are not really lengthening these muscles. Pulling the leg out and keeping the hip forward during leg lifts is difficult, since it is not a natural position for the muscles to be in.
What Are Leg Raises? The leg raise, also known as the straight leg raise or the lying leg raise, is a bodyweight exercise that targets your abdominal muscles, particularly the lower abs.
Placing a pillow between your legs can help reduce muscle tension by preventing your legs from pulling, providing you with a better night's sleep and less pain and undue stress on your back in the morning.
If your knee hurts, you might want to stay off of it. But resting too much makes your muscles weaken and often makes knee pain worse. Find a way to get moving without hurting your knee. Some good exercises for people with knee pain include walking, swimming, and water aerobics.
Ice and elevation.
To control pain and swelling, apply ice to your knee for 15 to 20 minutes every 2 to 4 hours. When you ice your knee, be sure to raise your knee higher than the level of your heart.
