Seated leg extension is an isolation exercise aimed exclusively at developing the muscles of the front of the thigh - the quadriceps. There is no need to maintain balance, and for this reason, stabilizer muscles are not involved in the work. The machine itself has a seat with a backrest to support the spine, which makes it safe.
The seat of the exercise machine is made of polymer that is resistant to the atmospheric environment and UV radiation. (aesthetically pleasing, ergonomic and safe)
The contact points of the gym are isolated - they have a polymer coating (there is no need to grip the “bare” metal, the possibility of conducting classes in the cold season)
How to exercise correctly
When performing leg extensions, the main load falls on the quadriceps muscle of the thigh, that is, the quadriceps. It is the largest muscle in the human body and its main function is to extend the knee joint and straighten the leg.
- Sit in the machine, press your back against its back and put your feet behind the roller
- With your hands, grab the special handles on the sides of the seat
- Raise your toes up
- As you inhale, smoothly straighten your knees. Tighten your quadriceps as much as possible at the top point, hold in this position for 1–2 seconds
- As you exhale, lower your legs down under control, but do not bend them all the way. That is, even at the lowest point, the quadriceps should be tense.
- Watch the sensations in your knees, do not suddenly throw your legs down.
