Strong glutes for the 'horsepower' factor

Kelly Baggett is an Arizona-based "performance consultant" who specialises in "increasing raw explosiveness, acceleration and jumping ability." In an article on his site Higher-Faster-Sports.com titled "The plague of the mediocre athlete; no glutes equals no results," he claims that the main difference between average and good athletes is in "the functionality of the feet, as well as the strength, development, and function of the glute musculature."

Baggett argues that the glutes are mainly responsible for the 'horsepower' factor and does not believe that an athlete can have too much glute strength. He maintains that "due to their natural strength and the leverage advantage they have over your legs, the glutes should always be the primary muscles that drive lower body movement.



Inhibited glutes and overshadowed glutes

In extreme cases the glutes may be inhibited to the extent that they don't contract when walking, standing or even playing sport, but the more common problem for the athlete is having "overshadowed glutes":



Here the glutes DO fire correctly, but are not as strong as other lower body muscles (like the quadriceps), thus the body will use other muscles to do what the glutes SHOULD be doing, resulting in inefficient
performance and often some type of pain or injury over the long haul. Whenever you perform a movement such as a squat, lunge, deadlift, jump, sprint, or any exercise that involves several different muscle groups, the majority of work will tend to be done by the strongest of those muscle groups.


People who don't have superior glute activation patterns and whose glutes are not naturally stronger than their thighs perform exercises in the weightroom that should be strengthening their glutes but typically end up with most of the strengthening occurring in the thigh muscles. Then "when you throw them into an athletic environment the body will naturally use the strongest muscles to control movements, so now their quads and other muscles will want to do what the glutes should be doing." People who tend to easily develop massive quadriceps are usually not very impressive athletically:


A person with overly developed quadriceps and lack of hamstring and glute development will tend to be a heel to toe runner and have trouble gliding, planting, and getting off on the balls of their feet. ... Even if the posterior chain is developed, in someone that has massive quadricep development, they will still struggle with ideal movement patterns because their body will try to do things that favor the stronger muscle groups.

Extensor dominant movement for speed



In another article, "Squats and speed development?" Baggett suggests that blazing speed derives from "extensor dominant movement." He advises:



for speed development you get away from focusing on exercises where you "bend your knees" and focus on exercises where you extend your hips. So, get away from squatting and focus on extending, where the focus is high RPM strength, which I truly believe a person can never have enough of. That means everything on the backside of your body becomes more important.

Hip-joint-specific strength apparatus



MyoQuip's latest release, the MyoHip, provides a biomechanically efficient means of exercising and strengthening the hip extensors - glutes and hamstrings - without activating the knee extensors. In addition it is very effective in strengthening and enhancing the functionality of the hip flexors, which are the antagonists of the hip extensors.

Announcing the MyoHip - the ultimate hip joint strength machine from MyoQuip


At last! A single simple-to-operate apparatus that effectively develops the all-important muscles of the body's great hinge mechanism - the hip joint - in both opening and closing; extending and flexing.

Despite its critical importance for human motion and posture, the hip joint has been basically neglected in terms of specific exercises and apparatus to improve its strength and functioning.

The primary hip extensor, the gluteus maximus, is the largest muscle in the human body. Very coarse in texture, it is heavily endowed with fast-twitch fibres. As a result it plays a central role in sports which involve sprinting and jumping. Conventional methods of strenthening and developing the glutes such as the barbell squat simultaneously activate the knee extensors or quadriceps. As a result optimal development of this vital muscle group is rarely achieved.

The MyoHip is unique as it is an accommodating or variable resistance machine which isolates the glutes and its synergistic muscles. Therefore the exerciser can focus on developing that muscle group. The possible range of movement for the exerciser on the MyoHip is 45° either side of the vertical, meaning that the included angle of the hip joint can extend from 45° to 135°, sufficient to ensure strong muscle activation.

The sequence below shows the apparatus being used in extension mode with the exerciser's back to the roller pads:



With modern sedentary lifestyles and the general aversion to walking anywhere, it is not surprising that many people have tight hip flexors which do not function effectively.

In order to use the MyoHip to develop and strengthen the hip flexors the exerciser simply changes their seating position to face the roller pads. The handgrips can be used if the pressure of the roller pads on the chest is uncomfortable. As in extension mode the exercise range can extend from 45° to 135° included angle of the hip joint.

In both extension and flexion modes the variable resistance mechanism compensates for gravitational attraction on the user's upper body. At the start of either movement the user has to overcome the effect of gravity on their trunk and head, while at the finish gravity makes it easier to push the roller pads. Therefore the machine's resistance is configured to become progressively greater throughout the exercise movement.

The sequence below shows the apparatus being used in flexion mode with the exerciser facing the roller pads:



Strengthening and developing the human body's great hinge, the hip joint

The MyoHip is an important addition to the exerciser's arsenal of strength-building equipment. For too long the muscles of the hip joint have been largely ignored. To some extent this could be because most exercises were originally developed and popularised by body builders whose desired body shape does not include large buttocks. They also have little interest in the hip flexor muscles since they are deep-seated and not visible.

However, for a large range of sports the hip extensors and flexors are vital. These include those sports where sprinting or jumping is involved and also rowing where the trunk swing is a major contributor to the power of the rowing stroke

Even more importantly a large proportion of the population experiences hip joint dysfunction. The MyoHip offers a very convenient and effective way to avoid these problems or to undertake rehabilitation.

Fast-tracking the development of young rugby players in the four "esses" - size, strength, speed and skill

A two-year program of accelerating the physical and skill development of young players at Sydney University has returned big dividends.

Within days of losing the 2006 First Colts Grand Final due to being out-muscled at the breakdown, University coach Nick Ryan met with his team and together they made a pact to never again be pushed off the ball. The players allowed themselves a mere three weeks break before getting back into training for the 2007 season at a level of intensity not seen before in Sydney club rugby. The off-season training regimen consisted of 4 weights sessions and 3 field sessions per week, switching to 3 weights and 2 to 3 field sessions during the playing season plus regular individual video analysis and field sessions with the coach.

The central ingredient of the training has been the strength and conditioning components devised by Martin Harland and administered by him and his assistant, Tim Leahy. "I guess we have two training tenets" Harland explains, "that is to always train hard and to train hard in the right areas. Thus developing the culture of no short cuts and to attend to the things in a prioritized plan from what we lack the most or what will help us the most on the park." Harland's programs for rugby players place a high degree of emphasis on basic strength development, increased bodyweight and speed. At the same time, given the year-round training commitment, great care is taken to guard against player burnout.
"We are consistently monitoring signs of overtraining," says Leahy. "Our in-season training structure does differ from our pre-season regime. The two key factors that help us guard against overtraining and player burnout is to firstly ensure our players are educated and understand the importance of post-game recovery strategies. "Secondly a close working relationship with coaching staff to ensure on field and gym volumes are of an optimal load. All variables as well as player’s subjective observation of energy, fatigue levels and contra indicators to injury are taken into account when prescribing volumes."

With a strong strength and fitness foundation laid, Nick Ryan and his team coaches are free to focus on technical proficiency and team cohesion. "The aim of our training sessions," says Ryan, "is to up-skill and empower the players, so that when they take the field not only can they read the game and make the right decisions, but then execute and finish off the activity with the help of team mates who are on a similar skill level and wave length." The payoff in terms of enhanced performance from the integration of strength and rugby coaching has been dramatic.

In the 2007 season University First Colts lost just one game out of 25 in winning both Minor and Major Premierships. Seconds and Under-19 Colts also won both Minor and Major awards. The dramatic improvement in the physical development of players can be seen from the Table below. As compared with the 2006 First Colts team, the 2007 forward pack's average bodyweight increased 5kg to 104.3kg; the backs 5.8kg to 86.2kg; and the team as a whole 5.3kg to 95.8kg.

The second year of intensive training produced even more impressive results. In the 2008 season all three Colts grades won both Minor and Major Premierships, with First Colts remaining undefeated throughout their 24-game season. Despite the age limit for Colts having dropped from Under-21 to Under-20, players' bodyweights again increased by 0.2kg for the forwards; 2.8kg for the backs; and 1.5kg overall.

"physical domination ... has enabled us to build a very strong defensive wall and to implement a highly structured game plan which we can maintain for the full 80 minutes."

To put the 2008 figures in perspective the Table also shows the bodyweights of the best professional rugby players in Australia, the current Wallabies squad. They outweigh this club-level Under-20 team by just 6kg per man in the forwards and 4.4kg in the backs. And this team of university students is currently on an unbroken 34-game winning streak! It is almost time for the administrators of Australian rugby to recognise and to take seriously the great experiment that is going on in their own backyard.Sydney University forward Ben McCalman finishing a tackle

Colts coach Nick Ryan has the extraordinary record of taking his team to the Grand Final in each of the 7 years he has coached; with his only loss the 4 point defeat in 2006. He says, " A very important outcome from the intensive training regime of the past 2 years has been our ability to achieve physical domination in matches. This has enabled us to build a very strong defensive wall and to implement a highly structured game plan which we can maintain for the full 80 minutes." As with the weight training, Ryan ensures that the field sessions are short and frequently varied, with the emphasis on having his team peak on Grand Final day in September. He certainly achieved this in 2008 with the winning scoreline 39-5.

In the regular season in 2008 Ryan's team averaged a 40-point winning margin and conceded only 8 points per game. Seconds and Thirds Colts also conceded just 8 and 5 points respectively per game.

A distinctive feature of the Sydney University rugby program has been its reliance on the MyoQuip range of strength building equipment. For the past four years the University gymnasium has been the primary development site for these machines. Not surprisingly MyoQuip's ScrumTruk and Hipnee Thrust* have been extensively used for lower body strength development. Martin Harland says, "These two lower limb extensor machines have been integral to training a wide cross-section of athletes in different sports at the University. In rugby they enable us to reduce the deleterious effects of heavy lower leg extensor exercises and on-field running loads. Traditional heavy squats & deadlifts are great for strength and size but are only moderately compatible with higher running loads for field or court sports. and incompatible with a sizeable subset of your player population for various reasons. To be able to de-load players spines while building hip & knee extensor strength through range of motion means more athletes able to train intensely in the gym and front up for intense speed & fitness work in the same week.” "

The combination of an intensive, well-structured and coordinated training regimen and the use of strength apparatus with high specificity for rugby can be seen to have produced accelerated physical development which has enabled players to perform at a consistently high standard.

*In recent months the University gymnasium has replaced its ScrumTruk and HipneeThrust machines with the more advanced and compact MyoTruk and MyoThrusta models.
