coach’s first important role we state:
In describing how assessing at athlete’s readiness to train and lift is the
Before an athlete begins training,
that athlete should be cleared by a medical professional to perform strenuous exercise in general and weightlifting in particular. While almost anyone can train to become a weightlifter, certain acute and chronic conditions preclude this. For instance, a person who has just torn his/ her ACL may well be able to compete in Weightlifting once the ACL has been repaired and rehabilitated, but not before that. Similarly, a person with a herniated disc is not ready to begin training until and unless that injury has been satisfactorily addressed, and perhaps not at all if such an injury is not fully resolved by treatment.
On the other hand, the more “experienced” beginners may have been performing a certain exercise so incorrectly
that it will take them longer to learn the correct exercise technique than someone who has never performed that exercise. Therefore, the new lifter with prior experience should be asked to demonstrate the relevant exercises he/she has been performing
to perform the snatch, clean, and jerk, such as the power clean and power snatch and any form of squatting or overhead lifting (e.g., front squats, back squats, push presses or military presses – exercises that will be explained later in this manual). If the athlete has no familiarly with these exercises, the coach should simply move on to the critical flexibility assessments we are about to discuss because

the use of proper technique and exposes the athlete to the possibility of injury.
new lifters with flexibility problems,
Performing flexibility exercises at the end of the workout and, in certain circumstances on non-training days, is essential for new lifters with flexibility problems, so that they can begin to learn the needed exercises as soon as possible.
raining for increased flexibility, it is strongly advised that:
When training for increased flexibility, it is strongly advised that:
1) only muscles that have been warmed up through a general or specific warm-up be stretched;
2) gradual increases on the range of motion are achieved during stretching and no sudden moves into the full range of motion are attempted;
3) only the current range of motion is sought during warming up and no effort is made to improve the current range of motion;
4) flexibility exercises cease as the specific warm-up progresses, and they are not resumed until skill building, and power and strength training during a given training session have been completed;
5) flexibility training to increase an athlete’s range of motion is performed immediately after strength training has been completed, while the muscles are still warm. Remember that the goal of training for an increased range of motion is to enable the athlete to comfortably and rapidly assume the correct starting and receiving positions during the competition lifts and related exercises. Progress toward this goal is tested by repeating the assessments described in the prior section of this manual. Only when an athlete has achieved the desired positions in all four assessments can unrestricted training on all lifts be commenced.
Remember that the goal of training for an increased range of motion is to enable the athlete to
comfortably and rapidly assume the correct starting and receiving positions during the competition lifts and related exercises.
One of the truisms of coaching is that
it is much easier to teach someone to lift correctly with no background in weightlifting than it is to correct the mistakes someone has been making for some time.
“The Universal Posture of Weightlifting
You will notice throughout the video footage the sequence photos of the snatch, the clean, the jerk, and virtually all of the other exercises weightlifters perform, lifters maintain a posture with these important characteristics:
1) the chest is inflated and “up” and shoulders are back as if the athlete is standing at attention; thus minimizing the natural curvature of the upper back (the upper back is never rounded or hunched);
2) the lower back is arched in the same way as it is when a person is standing at attention so that the natural curvature in the lower back is always maintained (never exaggerated nor diminished);
3) the head is vertical or looking slightly up, and the eyes are looking straight ahead or slightly upward. (maintaining the head in a vertical – upright – position is particularly important when the lifter is moving under the bar in the snatch or jerk, or when the lifter has a weight overhead, to keep the bar out of the upward/downward path of a rising/falling bar).
why good posture , about back and force
. Maintaining this posture at all times helps to protect the back from overstress and helps to assure that the tremendous force delivered by the legs and hips during the lifting process is transmitted directly to the barbell during all of the lifts, rather than having the force generated by the legs and hips dissipated through a torso that is sagging and absorbing the force of the legs.
Feedback on the posture via
Feedback on the posture via a video or mirror is often helpful as many beginners think they are maintaining a correct posture when they are not. I
Breathing
ift commences by lowering the bar (e.g., in the squat) the lifter normally holds that breath until the bar has been lowered to a position from which the lifting of the bar upward commences. Whether the lift begins with lowering the bar or with raising it (e.g., in lifting the bar from the floor), once the upward lifting has commenced (or immediately after it has been completed), the lifter exhales. If a lift is to immediately follow (such as a jerk after a clean or another repetition in the same exercise) the lifter takes a few quick breaths and holds the last one just prior to beginning the subsequent lift. Once the series of lifts has been completed, the barbell is replaced in its starting position and the lifter resumes normal breathing.
Only Two Grips Are Acceptable for New Lifters
Standard and Hook Grips,
Standard and Hook Grips
Hook No one quite knows when this grip was invented, but it is an incredibly powerful ally for all weightlifters who wish to lift maximum weights in the snatch and clean. The hook grip not only increases the amount a lifter can lift, but it helps to assure good technique, because a lifter who is struggling to hold onto the bar will tend to bend the arms during the pull, which is a clear and serious technical mistake and one that is very hard to correct once it becomes a habit
Thumbless grip
he grip that should never be used is the “thumbless” grip where the thumb and finger go around the bar in the same direction. This grip is not nearly as strong for lifting the bar from the floor as the hook grip, or even the opposing grip. While some lifters find such a grip more comfortable for the jerk, the likelihood of the bar’s slipping out of the hand during the jerk, or any overhead lift, is much greater than with the opposing grip, although the incidence of the bar so slipping with either grip style is extremely low. The thumbless grip is particularly dangerous in the bench press, where a falling bar can strike the lifter on the face, neck, or chest and trap the athlete against the bench, so this grip should never be used when performing this (or any other) exercise.
rack
Looking straight ahead and being guided to the rack by peripheral vision and gentle contact with the rear forks is a much safer and more effective strategy (the lifter should be careful not to push on the rear of the forks forcibly as this could tip the rack backward).
