Hi. I have a shoulder problem. I can ***** it and it hurts. I am not exactly sure what the problem is. I went to an orthopedist today and im not sure if hes a very good one. i always thought that playing tennis made my shoulder worse but the doctor said to play more tennis. he said there is nothing wrong with my shoulder. He said its just like cracking your knuckles. The problem is that it hurts. Should i listen to this doctor? One thing he told me to do is play more tennis and to do isometric exercises for my shoulder and neck. Can you give me a list of some good shoulder and neck exercises, along with how to do them? Thanks in advance.

I have a practice GCSE exam paper, but i am usure of the answer to one of the questions. I have searched the internet but i have not found the answer. Ten points to the first person who can get the correct and say why. Here is the question:

Isometric (muscle contractions without movement) exercises are designed to:

A| Develop more strength than isotonic (muscle contractions with movement) exercises.

B| Build strength only at joint angle used.

C| Strengthen the muscle throughout the range of movement.

D| Develop co-ordination.

Please state and explain the answer. Thanks

I am breastfeeding, and have been for three months now. I have about 40 pounds to lose to be at my pre pregnancy weight. I gained a TON, lol. But my question is this. Why do I seem to be GAINING weight, not losing when I am exercising every day (walking, swimming, dance dance revolution, isometric presses) and cutting calories?? BTW, my measurements have not gone down even a tiny bit either since the initial loss of my belly.
Oh, and P.S.–I had a cesarean delivery. If that makes a difference.

Jordan wanted to know:


okay ive studied just about every type of training there is, strength, cardio, functional, isometric, plyometric, fat loss, and just about everything else, and one thing ive noticed about each kind of training is that they all focus on one tiny aspect of your overall fitness, is there any sort of exercises i could do to improve everything or would i just have to do everything seperately?

I’m in Texas where requirements for becoming a personal trainer is rather low, anyway, I’m slender and fit and enjoy isometrics, weightless exercises, and water aerobics, and was wondering if I wanted to be able to train in those areas if I need to find a certification class that covers them and what is the easiest way to go about finding such a course. I’ve been told that a lot of personal trainer programs for certification is like going through a boot camp, is this true?
stu: as there are many different people of which different exercise programs work best for each one, I’m only concerned about what I like and those who are interested in what I like, I can’t be everything to everyone and don’t desire to be, I’d rather specialize and enjoy what I do and help those with similar goals… by becoming broad I’m actually becoming no different than anyone else

Hey,
I have Marfans Syndrome, and though I am skinny, I would like to lose fat and get more toned (or just lose fat ) I know there’s no way to “target” areas, but I need ideas for exercise that are “marfan-compatible” (i.e. no isometric exercise, no cardio)- mostly low-impact stuff. The problem is that I have the attention span of a puppy, so things like bike riding and walking are kind out out. I know swimming’s the best option, but I don’t want chlorine to damage my hair (sounds silly, i know)… I was wondering if I could do LIGHT weights- the other day I did lying leg curls, and they really worked out my hamstrings. I used only 5 kg/leg… Is this okay, or should I go even lower with the weights? And even if I did use really light weights, how would that be in relation to blood pressure?
Thanks!

Wikipedia defines PNF like this:

A combination of passive stretching & isometric contractions. “However, it can also weaken muscles, decrease endurance, slow neuromuscular control & coordination, & decrease joint stability.”

When resistance is applied, as in the case of Hold-Relax, it should be the max amount of resistance that allows for pain-free movement. “PNF exercises can be applied to patients of all ages. Research shows it is superior to static stretching.”

I understand what “passive stretching” & “isometrics” are, but can someone explain the contradiction I see in the two above sentences? Maybe its not a “contradiction”, but I’m looking for other people’s thoughts on PNF. They talk about it the my DVD, “Viniyogatherapy For The Upper Back, Neck & Shoulders”. I’ve got a torn rotator cuff & biceps tendon that caused my shoulders to tighten up over a period of months. Now I have a “clicking” in my neck with minimal pain that I’m trying to work out. No insurance. Thanks

Aerobic, Anaerobic, Isokinetic, Isometric
An exercise that uses special machines that provide resistance and control the speed of contraction within the range of motion.
Any physical activity that is short, explosive, depends solely on the energy that is stored in a muscle, and not on oxygen intake.
Any rhythmic, repeated physical activity that uses either or both your arms and legs, and requires large amount of oxygen for an extended period of time.
An exercise in which muscles are contracted and held for a few seconds, but the body doesn’t move.
