Muscle Up – Legs


Most people hate Legs Day.  That is a fundamental truth of weight training and regrettably, is usually the cause for more injuries and back pain than any other single factor.  Most people will rationalise this decision with the reasoning that they are ‘on their feet’ all day or, they are a tradesman and do heavy work all day.
On the surface, both reasons make good sense and you would be forgiven for thinking that the reasoning is based in fact.  The reality is that being ‘on your feet’ all day or, doing heavy work will do nothing by tire the muscles out.  In order to grow stronger and/or bigger, muscles need to be continually challenged to do more work (lifting) and then allowed to rest and recover.  Because our legs are in use from the moment we climb out of bed in the morning until we crawl, exhausted, back under the covers at night they get precious little time to rest and recover.  Frankly, if you are not challenging your leg muscles regularly, they are not going to need to rest and recover and will not get stronger or bigger.
In sport, the strength of, and speed of recovery of, your leg muscles will literally make the difference between winning or losing.  Without power and endurance, you will never be able to deliver a blistering shot at goal or, endure an Ironman triathlon.  In addition to building strength, power and endurance in your legs, you absolutely must spend at least 30 minutes every day stretching your legs and hips.  This practice will allow you to kick harder, reduce the risk of injury and maintain good joint mobility and flexibility.
A word of caution; while performing the following exercises, ensure that you never fully lock the knees.  Keep the knees flexed slightly, even at the top of a movement, at all times and this will protect the integrity of the joint and not place the many ligaments, tendons and menisci at risk of injury.

Leg Press

When you set up correctly for the Leg Press, it is one of the best all-around exercises for the entire lower body.  The Leg Press works the buttocks, quadriceps, hamstrings and calf muscles.  Most gyms will have one of two major variants of the Leg Press machine.  The best is the 45 degree Leg Press because of the negative load that is taken up initially.  The flat, or seated, Leg Press is in no way inferior, it simply does not offer the option of working the negative, or concentric, phase of the exercise.
45 degree Leg Press: Place your feet, shoulder width apart, on the foot plate at about the midway point, top to bottom.  Sit with your buttocks pressed at far back into the seat as possible, back straight and head up.  Push firmly against the foot plate to raise the weight off the support pins and release the locking bars.  Slowly lower the foot plate until your knees are at 90 degrees, pause then push the plate slowly back to the starting position to complete the rep.
Seated Leg Press: Position yourself in exactly the same manner as described above.  Slowly straighten the knees until your legs are almost straight (remember, do not lock the knees!).  Slowly lower to the starting position to complete one rep.

Dumbbell Lunges

This is a great hip and leg exercise and there are a number of postural factors that you must adhere to.  You must keep your head up and look straight ahead.  Your back must be straight, with shoulders back and down and your chest up.  Finally, maintain tension in your abs throughout the exercise.  Start by standing upright with a dumbbell in each hand and arms fully extended by your sides.  Feet should be shoulder width apart.  Step forward with your left foot, farther than you would with a normal step.  Your left leg should be bent at 90 degrees with your knee behind the toes.  The back leg should be bent at the knee, again at a 90 degree angle and the rear foot should not move, other than allowing the heel to lift off the floor.  Push back up to the standing position and repeat 10 or 12 times then repeat with the right leg forward.

Squats

This exercise has a number of different variations but the one we will look at here, is what is known as the back squat.  The back squat is conducted with a weighted barbell held across the shoulders, behind the neck.  The bar should rest naturally on the rear of the trapezius muscle and not on the neck.  Hold the bar with your hands wider than your shoulders, palms facing forward.  Bend at the knees and hips, leaning your upper body slightly forward, until your thighs are parallel to the ground.  Pause for a second and straighten your legs to return to the upright position.  Repeat the desired number of times.

Leg Curls

Leg Curls are to your legs what biceps curls are to your arms and, as is the case with your arms, we need to focus on achieving balance.  All of the preceding leg exercises have been focussed predominantly on the quads and glutes.  The hamstrings have been involved, in a supporting role, but have not really been pushed to the limit.  There are two types of leg curl machine available in most gyms, the seated leg curl and the lying leg curl.  My personal preference is for the lying leg curl because I feel that it isolates the hamstring muscles more.  For the purposes of this section, I will assume you are using a lying leg curl machine. 
Lie on the machine ensuring that the pivot point for the lifting arm is aligned with the centre of your knee.  Hook your ankles behind the lifting pads, your knees should be resting just beyond the edge of the bench.  Hold onto the bench legs, or handles if they are provided.  Lift the weight by bending the knees and keeping your pelvis firmly anchored to the bench.  Continue lifting until your lower legs are perpendicular to the ground.  Slowly lower to the starting position.

Leg Extensions

Many of you who have used a gym before will be wondering why I have not included a Leg Extension exercise.  The reasons are many, varied and complex but in a nutshell, for a novice or beginner exerciser, they can be dangerous.  If you are experienced in weight training, all of the connective tissues and supporting muscles in and around the knee capsule will have been conditioned to the stresses that the leg extension applies to the knee, particularly with heavier weights. 
If, on the other hand, you are not experienced in weight training the shear forces that are applied to the knee during a leg extension can be severe enough to cause major, and sometimes permanent, damage.

Next week, we delve a little deeper into the anatomy and have a close look at the major joints.
