EXERCISE, FITNESS AND NUTRITION NOs AND DON'Ts

by Cary Raffle MS CPT Master Trainer

Hardly an hour goes by at the gym that I don't find someone doing something that is not really helping them and might eventually hurt them, including:
• Incorrect Exercise Form
• Inappropriate Exercise Selection
• Obsolete Exercises
• Ineffective Exercise Programs
• Things that Look Good but Don't Make any Sense (most of these don't really look good they just think they do)
• Poor Nutritional Habits
This is the first time I have attempted this project, I've searched the internet and the books and can't find anything else like it all in one place. I'll be working on adding to it over time, and I invite you to clip the list and email me with any suggested additions for future editions.


NO BEHIND NECK PULLDOWNS!
NO BEHIND NECK SHOULDER PRESSES!

NO UPRIGHT ROWS (FRONT ROWS)!
You may as well kiss your rotator cuff goodbye. These exercises are obsolete - they have been shown to cause injury or impingement of the rotator cuff muscles over time. In addition, they provide no meaningful advantage to other exercises.

DON'T ARCH YOUR BACK!
An arched back causes pressure on the spinal column, it can lead to damaged disks and vertebrae. Lower the weight, use a machine with back support, and strengthen your abdominal core if you find yourself arching. Be especially careful about this when doing any overhead exercises, the leverage of the weight increases the likelihood of injury.

DONT WORK THE SAME MUSCLES 2 DAYS IN A ROW!
Strength training damages your muscle fibers. Muscles recover, repair and actually grow during the 48 hours after your work them. You won't see progress and you increase the risk of injury if you don't allow the rest. This applies only to strength training, you can do cardio every day.

DON'T USE THE SAME EXERCISE PROGRAM FOR MORE THAN 6 WEEKS
Your body adapts to an exercise program within 4-6 weeks, so you won't see much progress. You also increase the risk of repetitive stress injuries by continuing to perform the same motions at the same speed and intensity. Vary the exercises, weight, and tempo in your program at regular intervals.

DON'T DO THE SAME EXERCISES AS WHEN YOU WERE ON THE FOOTBALL (OR WHATEVER) TEAM OR IN THE MARINES!
Most of you are 5-50 years away from your high school and college sports days. You spend hours at a desk and commuting, and need to select exercises that are appropriate for grown ups who live a grown up lifestyle.

NO ROCKING, SWAYING OR BOUNCING!
If you an't stand still while performing an exercise, your using too much weight or doing something wrong for you. The exception is certain exercises where rocking or bouncing may be part of the exercise - for reference, this does not include biceps curls, shoulder presses, lateral raises, and most other exercises that I see people bouncing though.

DON'T SKIP MEALS - ESPECIALLY BREAKFAST!
Breakfast kick starts your metabolism and gives you the energy you need to exercise. If you're looking to lose weight, numerous studies have proven that people who eat breakfast are more successful at long term weight loss than those who don't. You'll have more effective workouts when your body had the fuel.

DON'T RELY ON BELTS, WRAPS AND BRACES!
The old fashioned weight belt may help protect your back, but over time it weakens your abdominal core because it is doing the job that you want to train your core muscles to do. No weight belts! Unless you're in the heavy-lifting phase of a power training program. Wraps and braces are a like a Band-Aid, they don't fix an underlying problem and in some cases transfer stress and problems to other joints. Talk to a sports medicine doctor or orthopedist before bracing, or that pain in your elbow may turn into an even worse problem at your shoulder.

DON'T WORKOUT UNTIL YOU WARM UP!
Spend about 5-10 minutes warming up with some cardio. Your muscles are less likely to get injured when they aer warm, and the warmup causes enzymes to be released that help protect the muscles and make your workout more effective.

NO LONG CARDIO SESSIONS BEFORE STRENGTH TRAINING
You'll get more out of your strength training if you have the energy to dedicate to the workout, and save the cardio for later or another day. If you've just run 5 or 10 miles, you're ready to eat, not to workout! (This one is dedicated to one of my highly conditioned clients who ran a quick 8 miles before a strength training session... and took an early leave to get a yogurt).

DON'T HOLD YOUR BREATH!
Proper breathing is to exhale on the concentric contraction, that is when you are actually shortening the muscle. It's the push phase on pushing exercises or the pull phase on pulling exercises.

NO UNNECESSARY SUPPLEMENTS!
Protein: According to the doctors at the American College of Sports Medicine, a 170 pound man needs about 131 grams of protein per day to increase muscle mass (1.7g/kg body weight) and about 100 grams to support endurance (1.3g/kg). If you're already getting that much in your diet, skip the supplement. More is not better!
Sports Drinks: Research shows that Gatorade-like drinks are effective when you're exercising or playing a sport for more than an hour, or if you like the taste and won't get enough fluids otherwise. Water is just as good if you're planning a 59 minute workout.
Creatine: Is one of the few supplements that has a long standing body of research, dating back almost 100 years. It shows no effect in aerobic performance, some short term gain in muscle size -believed by many to be increased water retention, and marginal improvement in strength or anaerobic performance.
Weight Loss & Energy Supplements: Most of these contain caffeine or guarana. Guarana contains about 3x the caffeine as coffee, and when it is included as an ingredient instead of caffeine, the manufacturer doesn't have to tell you how much caffeine is in the drink. Caffeine will help you lose weight, it raises your heart rate and is proven to increase fat metabolism, but would you have 3-4 cups of coffee? Taurine, also popular, has very little human research, which brings us to...
Other Supplements: Supplement makers can claim whatever they want. The government does not test nutritional supplements for effectiveness, safety, consistency, purity, or interaction with other drugs or conditions. Think about how often you hear about a drug that was FDA tested, or a supplement, that is later found to have harmed people. Do you really want to take that risk with your health?

IF YOU HAVE SHOULDER PROBLEMS, DON'T DO ANY OF THE FOLLOWING Overhead Exercises, Incline Chest Press (and possibly any chest press), Front Raises, Shrugs, Preacher Curls, Behind the Neck Triceps Extension All of these exercises put you at risk of further injury and pain. Have a detailed conversation with your doctor and/or physical therapist about contraindicated exercises, and consider consulting a personal trainer with post-rehab experience to design a safe and effective program.

DON'T DO ANYTHING THAT HURTS!
If something hurts severely, or hurts for more than a week, its time to see a doctor. Don't assume that you can lower the weight and not do any further damage, sometimes it is the movement itself that is the problem. Get a diagnosis so that you now what you are dealing with.

DONT FORGET THE WATER!
Those ACSM Doctors say bring your water bottle along and: Drink about 1-2 cups of fluid 30 minutes pre exercise, drink ½ - 1 cup of fluid for every 15 minutes of exercise, drink 2 ½ cups for every pound lost during exercise. Drink even after your thirst is quenched.

NO STRAIGHT LEG OR DECLINE SITUPS!
These cause the back to arch and risks damage to the spine. Bent leg situps are not much better. Do crunches instead.

NO LYING FULL LEG & HIP RAISES WITH A DUMBELL BETWEEN YOUR FEET!
Never hold an unsecured weight over your face.

NO LEG EXTENSION MACHINE!

Current expert opinions on this machine, for most people, range from its a waste of time to its something that could hurt you if you have any knee problems. Try some lunges instead.

IF YOUR BACK HURTS, DON'T DO ANY OF THE FOLLOWING Back Extensions, Good Mornings, External Abdominal Exercises, Unsupported Above the Head Exercises, High Impact Activities Generally avoid anything that makes your low back tighten and/or arch. Focus on strengthening your abdominal core - your deep abdominals, not the so called 6 pack muscles. In most cases, back muscles are overworking because the inner abdominal muscles are weak. Sitting at a desk all day is one thing that can make your abs weak and your back tight, so you'll want to progress to exercises that get you out of a seated position.

DONT FORGET TO STRETCH!
Stretch before and after you exercise. Get your muscles into balance by stretching the tight ones before you exercise to get your joints in proper alignment and avoid injury; after exercise, stretch the muscles that became tight during exercise. You don't have to stretch EVERY muscle, just the tight ones.

The Truth About Abdominals

If you want great looking abs, the first thing you need to do is reduce the layer of fat covering your abdominal muscles. The only way to burn fat is to have a calorie deficit: either burn more calories than you eat or eat less calories than you burn. You can do this through diet, exercise, or a combination of both. Resistance training of your large muscles - legs, chest and back - will maximize your calorie burn and may also help increase your resting metabolism as you gain lean muscle.

Abdominal Exercises strengthen your muscles but are not effective in reducing abdominal fat. You can have very strong abdominal muscles covered by a layer of fatty tissue. It is more efficient to spend the majority of your limited exercise time burning the fat than strengthening the abs. You cannot spot reduce - working the muscle in an area does not reduce the fat in that area, fat does not "turn into to muscle" they are two different types of tissue.
Most people will see definition in the abdominal area at around 9-12% body fat for men and 10-14% for women. This will vary from person to person, depending on where their body stores fat (sometimes called your body type). There are some theories about cortisol, a stress hormone, leading to increased storage of fat in the abdomen, but abdominal fat tends to be dictated mainly by your body type.

You don't need machines to effectively work your abs. Some of the most effective abdominal exercises don't use machines at all and some machines are actually less effective than plain old crunches. (See the next post for a report on the most and least effective ab exercises from the American Council on Exercise).

Most people focus on the rectus abdominus (6 pack muscle) and the obliques, but it is more important to work on the inner abdominal core. In fact, some people should avoid the most popular ab exercises altogether because it can exacerbate problems with posture and low back pain. Simple exercises that focus on activating the deepest abdominal muscle (the transversus abdominus) include a drawing in maneuver, balancing on one leg, planks, and quadrupeds with arm and leg raises. These core exercises can improve posture and pull the abdomen in, giving the appearance of a smaller and tighter stomach. You can also incorporate core training into your everyday exercise routine, click here for a sample program.

There is no conclusive evidence that you can work so called upper and lower abdominals separately. See ACE's study (sidebar) which showed that the abdominal muscles function as a single sheath.

Quality is more important than quantity. You don't need to do hundreds of crunches a day to have good looking abdominal muscles, and you don't need to use heavy weights. The abdominal muscles work slowly and work isometrically, they respond very well to being trained the same way. Increase the level of difficulty by varying the speed, adding isometric holds, and decreasing the stability of your abdominal exercises. You can get results by working for 15-20 minutes 3-4 times a week.

Not every abdominal exercise is right for everybody. If you're working with a personal trainer, your fitness assessment will help determine the best selection and any necessary modifications based on your own personal personal abilities, physical condition and goals. Just because you see someone else doing an exercise that looks interesting, or it is part of the routine in a group class, that doesn't necessarily make it right for you. Avoid any exercises that are painful to your lower back and exercises where you are unable to maintain proper form. In classes, if you have concerns or problems keeping up with the class, speak with the instructor or a personal trainer to determine whether you need to modify the exercise or perform an alternate instead. For example, a member recently complained to me about back pain and inability to work full range of motion while doing leg raises in abs class. Modifications could include bending knees during the exercise, placing hands beneath the tailbone or an alternate position.

The Best and Worst Abdominal Exercises

Research from the Biomechanics Lab at San Diego State University, commissioned by the American Council on Exercise.

This study measured activation of the abdominals muscles - the rectus abdominus (6-pack muscle) and obliques - for 13 different exercises.

The three most effective in terms of activating muscles are the bicycle, captains chair (leg raises) and stability ball crunches.

Some equipment, like the ab rocker, was far less effective than even traditional cruches.

The study also reported that most people are unable to separately trigger activation of the upper and lower ab muscles - suggesting that the muscles act together and not independently.
