"Dear Trish and David…
You mentioned that exercises can be designed to promote either strength, size, endurance, or shape. Exactly HOW does one accomplish this (in 500 words or less, please… I’m on the way to the donut shop!)
-Great and Getting Even Better in Glen Burnie"
Dear "Great"…
Obviously, you read our column weekly, and know WHEN to eat a donut… on the way to the gym! So we will get right to the point!
Skeletal muscles (the ones that keep you moving, AND looking sexy) are made up basically of TWO types of fibers. One is called "fast-twitch", and the other (bet you guessed it….) "slow-twitch". There are different combinations of these in various areas of the body.
The fast twitch fibers are the ones designed for POWER! Short duration, high intensity movements. Things like kicking the tires on a car before you buy it, or giving a great big bear hug to the aerobics instructor at the gym (OK… and LIFTING and PUSHING heavy weights, too!).
Conversely, slow-twitch are "endurance" fibers. They are vital in doing things like cycling, long-distance walking, or running away from the aerobics instructor after he slaps your face. Now that you know the difference… it empowers you to actually choose specific exercise types, patterns and sequences that will shape your, give you larger mass (in the right places), or give you greater and greater endurance!
After choosing the appropriate exercises for the objective and body parts that you want to work, you will decide on the number of SETS and REPS. This is critical, but relatively easy to determine. Here are the formulas:
Low Sets (1-2)/Low Reps(6-8)/High Resistance(GRUNT!) = Increased Mass
Moderate Sets (3)/Moderate Reps(9-12)/Moderate Resistance(Wipe my Glowing Brow!) = Increased Strength
High Sets (4-6)/High Reps(16-30)/Low Resistance(Is THIS all there is too it?) = Toning and Sculpting
This is simplistic, and in the real world of fitness (sounds like a dramatic series, doesn’t it?) we incorporate various combinations of these in order to get the desired results.
These variables, and a veritable plethora of others, totally shatter the image of the bodybuilder or fitness enthusiast being an empty-headed muscle geek. Making correct and effective choices takes a knowledge of physiology, kinestheology, psychology, nutrition, and many other disciplines (or the services of a Certified Trainer!).
Overall fitness is characterized by strength, endurance and flexibility. It is vital that your program enhances ALL of these areas. It is common to see people who are truly committed to honoring their bodies and increasing the quality of their lives make uninformed, and often self-defeating, decisions as to what to do to actually reach and maintain their fitness goals.
As is often suggested by Trish and I… get information, get support, and get fit!
The Bottom Line:
Different types and styles of exercise will give vastly different results. Make plans, and then GO FOR IT!
