What are the essentials of the Best Seated Leg Extension & Curl in china?

Essentials of the Best Seated Leg Extension & Curl in china

1. In the Best Seated Leg Extension & Curl in china exercise, you will need to use the Best Seated Leg Extension & Curl in china instrument. First, choose the weight, sit on the Best Seated Leg Extension & Curl in china instrument, with both legs under the mat (toes of both feet pointing forward), and grasp the handle on the side with both hands. This is the starting position of the action. Tip: you will need to adjust the mat so that it falls on the lower part of your leg (above your feet). Make sure your legs are at an angle of 90 degrees between your big calves. If the angle is less than 90 degrees, it means that the knee exceeds the toe, which will exert unnecessary pressure on the knee joint. If the instrument is designed like that, either change another instrument, or make sure that when you start practicing, once you reach the angle of 90, you stop downward.

2. While exhaling, stretch your legs to the maximum with your quadriceps. Make sure the rest of your body stays still in the seat. Hold in the tense position for 1 second.

3. While inhaling, slowly reduce the weight to the original position and make sure you don't exceed the limit of 90 degrees.

Misunderstandings of the Best Seated Leg Extension & Curl in china

1. The upper back is too backward

The upper back of the body is too backward, rather than pressing the hips and lower back close to the stool. The sitting posture is very relaxed and lazy, so there will be a lot of space behind the body. As a result, you can only do half-way movements, and the range of movements is greatly reduced, reducing the stimulation to the quadriceps femoris.

2. Leaning forward

When quadriceps femoris contract and lift up, don't lean forward, and don't lift gluteus maximus by force, which will exert great pressure on the waist and easily cause waist injury. The main reason is that the load of practice is too large, and you don't pay attention to the details of the action. At the beginning of practice, don't put too much load on it, but step by step.

3. Use inertia of the Best Seated Leg Extension & Curl in china

Just throw up the weight without peak contraction. Just like using inertia, throw out the weight quickly, and even let the instrument leave your feet. This is useless.
