21 rewards of exercise…

By Steve McKinney

Today I offer an excellent list of 21 rewards of exercise…

1. You’ll reset your body: Exercise has been described as a giant reset button. A good workout will block appetite swings, improve your mood and even help you sleep.

2. Your clothes will fit better: Consistent exercise will tone and tighten your body, causing your clothes to not only fit better but to also look nicer. Also exercise ensures that soon you’ll be trading your clothes in for smaller sizes.

3. You’ll be less stressed: You have enough stress in your life—it’s time for a break. A good workout invigorates your muscles, leaving you relaxed and less stressed.

4. You’ll have more energy: WebMD tallied research studies and concluded that 90% prove exercise increases energy levels in sedentary patients. Next time you feel fatigued, fight it with the most powerful tool available: exercise.

5. You’ll be stronger: Exercise improves muscle strength and endurance, two things that you use throughout each day. When you exercise consistently you’ll be pleasantly surprised when difficult tasks begin to seem easy.

6. You’ll be less likely to binge: Exercise has a powerful anti-binge effect on the body. This is due in part by an increase in sensitivity to leptin, a protein hormone, which has an appetite-taming effect.

7. You’ll burn calories: You know that excess body fat is made up of stored and unused calories. Fight back by burning loads of calories with fat-blasting workouts.

8. You’ll be more confident: Who doesn’t wish they walked and talked with more confidence? A consistent exercise program will do just that. As your body becomes more fit, watch as your confidence sky-rockets.

9. You’ll have fun: Believe it or not, exercise can be extremely enjoyable. Remember how fun it was to run around as a child? Tap into your inner child as you find a mode of exercise that gets you excited.

10. You’ll reduce your blood pressure: Exercise has been proven more effective than medication in reducing blood pressure to normal levels. A single workout has been shown to reduce blood pressure for the day and regular exercise reduces overall blood pressure in the long run.

11. You’ll lose the jiggles: Regular exercise tightens flabby arms, legs and waistlines. So wave goodbye to the jiggles with a solid exercise program.

12. You’ll increase insulin sensitivity: Researchers at Laval University in Quebec discovered that exercise improved insulin sensitivity dramatically. Peak after-meal insulin levels dropped by more than 20 percent after as little as 3 weeks of consistent exercise.

13. You’ll sleep better: Do you toss and turn for hours before falling asleep? Exercise is a powerful sleep aid. Your tired muscles encourage your body to quickly fall asleep so they can get their overnight repair work done.

14. You’ll lower your risk of heart disease: Regular exercise strengthens your heart and makes it more resilient against disease. A sedentary lifestyle is a major risk factor for heart disease, so rest assured that consistent exercise is your ally against disease.

15. You’ll feel great: Vigorous exercise releases natural endorphins (happy hormones) into your blood stream that dissolve pain and anxiety. You’ve probably heard of ‘runner’s high’, this can be achieved by any great workout.

16. You’ll lower your risk of diabetes: Studies show that exercising as little as half an hour each day can dramatically reduce your risk of diabetes. If you are at risk of diabetes, or already have diabetes, regular exercise is the most effective treatment for reversing the disease.

17. You’ll meet cool people: You could benefit from a group of new, energetic friends, right? Gyms, bootcamps, workout centers and even the jogging trail are all great places to connect with fun new friends.

18. You’ll improve your BMI: You know that maintaining a healthy BMI is key in disease prevention. Exercise is the best way to keep your BMI under control.

19. You’ll increase your endurance: Do you ever get out of breath when walking up stairs or through the mall? Regular exercise builds your endurance for everyday activities.

20. Your doctor will be impressed: How many times has your doctor given you the lecture about losing weight and exercising more? Exercise regularly and get your MD off your back!

21. You’ll look amazing: Are you happy with the shape and size of your body? Regular exercise works wonders on your physique. Within a few weeks you’ll see shape and tone in all the right places.

High Intensity Strength Training For Better Body Composition

Submitted with permission by: Wayne L. Westcott, Ph.D.

During the past several years we have learned a lot about the effects of strength training and body composition. For example, a carefully controlled study at Tufts University showed significant changes in body composition from a basic program of strength exercise (Campbell et al. 1994).

The subjects added three pounds of lean weight, lost four pounds of fat weight, increased their resting metabolic rate by seven percent and increased their daily energy requirements by 15 percent after 12 weeks of strength training.

Research with over 1100 previously sedentary adults revealed similar body composition improvements from eight weeks of standard strength training (Westcott and Guy 1996). The program participants increased their lean weight by 2.4 pounds and decreased their fat weight by 4.6 pounds.

Of course, unfit individuals tend to improve their body composition at faster rates than people who are presently doing strength exercise. Many people want to know if strength training can further enhance body composition in well-conditioned exercisers.

Previous studies have demonstrated that various high-intensity training techniques are more effective than standard training protocols for increasing muscle strength in both beginning and advanced participants (Westcott 1996, 1997a, 1997b; Westcott and La Rosa Loud 1997). As shown in Figures 1 and 2, slow training produced greater strength gains than standard training for both beginning and advanced trainees. As illustrated in Figures 3 and 4, breakdown training resulted in greater strength gains than standard training for both beginning and advanced exercisers. Likewise, assisted training generated greater strength gains than standard training for both beginning and advanced subjects (see Figures 5 and 6).

We have recently examined the effects of combined high-intensity training techniques on body composition changes in well-conditioned participants. The six-week advanced exercise program included slow training, breakdown training, assisted training, and pre-exhaustion training. The 48 subjects added 2.5 pounds of lean weight and lost 3.3 pounds of fat weight as a result of their training efforts, which represented more improvement than we expected from regular strength exercisers.

We have been pleased with our participants’ positive response to the combined approach of high-intensity strength training techniques. Our standard exercise protocol is outlined in Table I.

We observed that many program participants selected the pre-exhaustion technique for their sixth week of high intensity training. Although we do not have data that show this training method to be better than the others, there may be some benefit in performing more pre-exhaustion sessions. Psychologically, changing exercises at the point of muscle fatigue may be more appealing than performing more repetitions of the same movement pattern with less weight or with manual resistance. Physiologically, performing two different exercises for the target muscle group recruits more muscle fibers which may enhance the training stimulus. In addition to more exercises, pre-exhaustion programs require more training time and may therefore be the best high-intensity technique for burning calories.

Table I: Standard Exercise Protocol

Week Days	Training Technique	Total Exercises	Total Time
1. M & F	Breakdown (10 reps to fatigue plus 3 reps with 10-20% less weight)	12	20 Minutes
2. M & F	Assisted  (10 reps to fatigue plus 3 reps with  manual assistance)	12	20 Minutes
3. M & F	Slow Positive  (5 reps to fatigue with 10 seconds lifting and 4 seconds lowering)	12	20 Minutes
4. M & F	Slow Negative  (5 reps to fatigue  with 4 seconds lifting and 10 seconds lowering)	12	20 Minutes
5. M & F	Pre-Exhaustion (10 reps to fatigue with first exercise plus 5 reps with second exercise)	16	25 Minutes
6. M & F	Personal Preference  (Trainee chooses the technique that seemed most productive)	12-16	20-25 Minutes

As many of our intermediate level strength trainees want to improve their body composition, we presently provide high-intensity training programs with more emphasis on pre-exhaustion techniques (Table II). The results are encouraging, but we try to be cautious about overtraining. Our members seem to respond well to six weeks of high-intensity training followed by six weeks of standard training to maintain their new level of strength and fitness.

Although we have not previously provided nutritional counseling to our high-intensity training participants, this would undoubtedly be beneficial for clients who want to lose fat as well as build muscle. A combination of individualized high-intensity strength exercise and sound dietary guidelines should produce significant improvements in body composition.

Table II: High Intensity Training Techniques

BASIC DESCRIPTIONS
Name	Procedure	Example	Comments
Breakdown Training	Perform about 10 reps to fatigue with standard weightload. Immediately  reduce resistance 10-20%  and perform about 3 more reps to second level of fatigue.	Complete 10 leg extensions with 150 lbs., then 3 more reps with 120 lbs.	Change resistance as quickly as possible  to maximize the training effect.
Assisted Training	Perform about 10 reps to fatigue with standard weightload. Trainer assists with 3 post fatigue reps on lifting  phase only.	Complete 10 leg extensions with 150 lbs., then 3 more reps – with manual assistance from trainer.	Assistance is given only on the positive muscle action where it is necessary, but not on the stronger nega- tive muscle action when it’s unnecessary.
Slow Positive Training	Perform about 5 reps to fatigue with 10% less than standard weight-load, taking 10 seconds for each positive muscle action and 4 seconds for each negative muscle action.	Complete 5 leg extensions with 135 lbs., counting 10 secs up and 4 secs down for each rep.	Be sure to breathe continuously throughout every repetition.
Slow Negative Training	Perform about 5 reps to fatigue with 5% less than standard weightload, taking 4 seconds for each positive muscle action 10 seconds for each negative muscle action.	Complete 5 leg extensions with 142.5 lbs., counting 4 secs up and 10 secs and down for each rep.	Use smooth and continuous move- ments, rather than choppy stop and go movements.
Pre-Exhaustion Training	Perform two successive exercises for target muscle groups, typically a rotary exercise followed immed- iately by a linear exercise. Use 10 reps to fatigue in the first exercise and 5 reps to fatigue in the second.	Complete 10 leg extensions with 150 lbs., then 5 leg presses with 300 lbs.	Take as little time as possible between the two successive exercises to maximize the
