Name of the exercise - Hack Squat.

Prime muscle - Quadriceps and Gluteus Maximus
Plan of movement - Sagittal plane
Synergist (assisted muscles) - Gluteus Maximus ,Adductor Magnus and Soleus
Stabilizer muscles - Hamstrings and Gastrocnemius
Movement - Knee extension and Hip extension
Force - Push
Mechanic type- Compound
Execution:
1) Lie supine on back pad with shoulders under shoulder pad. Place feet shoulder width apart on platform. Extend hips and knees and release lever.
2) Flex hips and knees to descend until knees are just short of complete flexion. Raise sled by extending knees and hip. This is one repetition.
Cautions/guidelines:
1) Do not lower the weight so far that your hips start to curl up off the seat! Then slowly push the weight back up using your heels, not your toes. If insufficient hip flexibility forces the pelvis to pull away from the back pad at the lower portions of the movement, only lower the sled just short of spinal articulation.
2) Keep knees pointed same directions as feet.
3) Do not allow heels to raise off of platform, pushing with both heel and forefoot.
4) Same exercise can be performed for adductor group of muscle with wide stance feet (around 2 feet). 5) Do not lock your knees at the top.


Name of the exercise - Lunges(Dumbell,Barbell)

Prime muscle - Quadriceps and Gluteus Maximus
Plan of movement - Sagittal plane
Synergist (assisted muscles) - Adductor Magnus and Soleus
Stabilizer muscles - Erector Spinae ,Tibialis Anterior ,Gluteus Medius ,Gluteus Minimus
Movement - Knee extension and Hip extension
Force - Push
Mechanic type- Compound
Execution:
1) Stand with dumbbells grasped to sides, set your feet shoulder width (1 foot) apart and toes pointing slightly outwards.
2) Lunge forward (with first leg) placing the foot outwards and slightly wider. Land on heal then forefoot. Lower body by flexing knee and hip of front leg until knee of rear leg is almost in contact with floor.
3) Stand on forward leg with assistance of rear leg. Lunge forward with opposite leg. Repeat by alternating lunge with opposite legs. This is one repetition. Same exercise can be done by holding barbell on the trapezius muscle.
Cautions / Guidelines:
1) Bigger the step the more gluteus maximus of the front thigh will be engaged.
2) Smaller the step the more quadriceps of the front thigh will be engaged.
3) Always start with light weights.
4) Do not lunge forward exactly in the line of back foot, Lunge in slightly lateral side.
5) While descending, knee should not rotate internally.
6) Keep head forward, back straight


Name of the exercise - Leg Extension Machine

Execution:
1) Sit on leg extension machine with back against padded (cushioned) back support. Place front of lower leg (shins) under padded lever. Position knee articulation at same axis as lever fulcrum.Grasp the handles on the machine or the edges of the seat to keep your hips from lifting up as you perform the exercise.
2) Extend your legs until knees are straight, making sure you remain seated flat on the machine. Raise the weight all the way, lock and hold for 2-3 seconds, then slowly lower the weight back to the starting position. This is one repetition.
Cautions / Guidelines:
1) Lower the resistance if you have to get off the seat while lifting the resistance.

Name of the exercise - Barbell Squat(dumbell,exercise tube)

Prime muscle - Quadriceps and Gluteus maximus
Plan of movement - Sagittal plane
Synergist (assisted muscles) - Adductor Magnus and Soleus
Stabilizer muscles - Erector Spinae , Deltoid (Anterior& Lateral) ,Supraspinatus ,Pectoralis Major, Clavicular
Trapezius, Levator Scapulae ,Serratus Anterior, Rectus Abdominis and Obliques , Hamstrings ,Gastrocnemius
Movement - Knee extension and Hip extension
Force - Push
Mechanic type- Compound
Execution:
1) Place a barbell on a squat rack. Duck under the bar and position it across your shoulder on the trapezius, slightly above the posterior part of the deltoids. Dismount bar from rack.
2) Move back a step or two from the rack and set your feet shoulder width (1 foot) apart and toes pointing slightly outwards.
3) Inhale as you slowly bend your knees and descend until thighs are just past parallel to the floor. Exhale as you extend knees and hips until legs are straight (starting position). This is one repetition.
4) Exhale when you come up and inhale when you descend.
5) Taking a deep breath to fill the chest and holding it fills the lungs like a ballon, which makes the rib cage rigid and prevents the torso from tilting forward. Contracting abdominal muscle group prevents the torso from tilting forward.
Cautions / Guidelines:
1) Knees should point same direction as feet throughout movement.
2) Keep head forward, back straight and feet flat on the floor; equal distribution of weight through fore foot and heel.
3) If the ankle is not flexible enough to allow the knee to travel forward sufficiently, the back will need to be bent forward more to maintain the center of gravity within the foot base. Until flexibility can be restored, a temporary solution is to elevate the ankles on a board or platform.
4) While descending, knee should not rotate internally.
5) Keep your head forward and back straight throughout exercise.
