Even though front squats do not stimulate the gluteus
muscles and the hamstrings as efficiently as back squats, they tend to have a greater impact
on the three
quadriceps heads.
Athletic bodies are not always skinny - swimmers require a level of body fat to improve their buoyancy, and downhill skiers require bulky
quadriceps, hamstrings and gluteal
muscles to counteract the forces operating
on them as they descend at high speeds.
The
quadriceps are the large
muscles on the front of your thigh that straighten your knee when walking or standing.
Once normal daily activities are pain - free then gentle stretching exercises may be beneficial along with sports massage for the
quadriceps and myofascial release techniques to help stretch the
muscles can help ensure they are strong enough to cope with the loads placed
on them as well as not being too tight.
If you read my article
on outer thigh exercises, then you understand that most of the outer thigh is actually the
quadriceps muscle that works
on the knee joint.
This implies that the benefits are durable, and continue to have a positive action
on restoring lost
quadriceps muscle mass for many weeks after essential amino acid supplements are taken.
It is a great workout to target all the stubborn fat
on your hamstrings, hip flexors and
quadriceps muscles.
For example,
on the «up kick» of a dolphin kick, the
quadriceps concentrically contract to bring the leg into extension while the hamstring, the opposing
muscle, eccentrically contracts as the leg swings forward.
Stretching
muscles that contribute to your back support (hamstrings,
quadriceps, abdominals, chest
muscles, glutes) can improve their ability to relax and contract, and reduce the load
on your back.
These are especially important when you work out your tush, since many people have pretty poor glute activation — i.e. their gluteal
muscles do not fire when they perform the exercises, and often it's their
quadriceps which end up taking
on the bulk of the work.
Based
on changes in
muscle activity with load, bar speed, and ROM, the prime movers in the back squat include the
quadriceps, gluteus maximus and erector spinae.
Let's talk a little about stride length: lunges with a long stride, place the emphasis
on your gluteal
muscles, while lunges with a short stride place it
on your
quadriceps.
To build strength around the knee (s) concentrate
on strengthening and lengthening the
Quadricep, Hamstring and Calf
muscles groups.
The
quadriceps muscles and other tissues such as the retinaculum are too tight
on the outside of the knee and the vastus medialis oblique
muscle is weak
on the inside of the knee.
For instance, if you are concerned with stretching
quadriceps, then a treadmill
on an incline or stepper works well to warm those
muscles up.
Standard (traditional) deadlifts use these same
muscles but also involve the
muscles on the front of your thighs — the
quadriceps.
The quads or
quadriceps femoris (Latin for «four - headed
muscle of the femur»), also called simply the
quadriceps,
quadriceps extensor, or quads, is a large
muscle group that includes the four prevailing
muscles on the front of the thigh.
Aside from helping to prevent injuries, there's another reason: thanks to the good old 9 - 5 spent sitting
on our tush, most people have weak glutes, tight hip flexors and tight hamstrings, which means if they dive straight into the exercises they don't target their glutes, but rather other
muscles like the thighs (
quadriceps in the front, adductors
on the inside and hamstrings at the back).
Your workouts must focus
on strengthening the hamstrings
muscles on back of thighs,
quadriceps on front of thighs and glute
muscles in butt.
Squats are great for toner legs since you will be working
on your calves, hamstrings and
quadriceps (i.e. the
muscles in your legs).
Often
on infomercials people talk about the outer thigh, but the outer thigh is formed by the
quadriceps muscle which is located
on the front of the thigh and wraps around to the outside of the thigh bone (femur).
Due to the more upright upper body posture, the Front Squat focusses strongly
on the
muscles on the anterior side of the thighs, the quads or
quadriceps (the
quadriceps consists of a group of four
muscles, the vastus lateralis, the vastus medialis, the vastus intermedius and the rectus femoris).
This exercise is also very effective in targeting the fat stored
on your legs and can do great wonder to those who are struggling with fat stored in their
quadriceps muscles.
Performed slow and controlled for moderate to high reps, they can actually strengthen the tendons of the patella, and depending
on how you position your leg, they can work all four sections of the
quadriceps muscle.

quadriceps muscle, just inferior to the anterior superior iliac spine.
Comparing the effects of carrying a dumbbell
on the contralateral or ipsilateral sides, Stastny et al. (2015) found no differences in the
quadriceps muscle activity between carrying positions.
You can incorporate variations of the squat, in order to target different
muscles more specifically: The front squat focuses more
on the
quadriceps, whereas the back squat (recommended over the front squat, because it recruits more
muscle activation) works the gluteals and hamstrings more.
When the
quadriceps muscle contracts, it pulls
on the patellar ligament and causes the tibia to straighten, resulting in extension of the leg.
Clinical Signs: Lameness that is often intermittent, and may be unilateral or bilateral; thick, swollen stifles; pain
on range - of - motion; crepitus; palpable luxation; inability to jump or walk normally; medial displacement of
quadriceps muscle group; lateral bowing of the distal third of the femur.
