Analysis of
“Curves” Fitness ProgramBy Kyle Battis CSCS, L/ATC, NSCA-CPT Professional Fitness Coaching
Many people have asked me what my thoughts were on
Curves fitness program. After researching
program, interviewing current and past members, and speaking with other fitness professionals around
country I have compiled
following analysis.
WHAT IS “CURVES”?
Curves is a franchised exercise program designed exclusively for women. The Curves program has spread across
nation like wildfire due to claims such as: “No experience necessary, only 30 minutes for a full-body workout, no class times, no appointments to keep, you can’t be late for your workout because
circuit is always on!” In fact,
Curves franchise is listed by Entrepreneur Magazine as one of
top franchises to own. The question is why has it grown so popular?
The answer can be found in
target audience of
Curves program. Curves caters to a very large group of women seeking positive physical change in a supportive environment. Most commercial gyms and fitness centers do not come close to offering a friendly and supportive environment for beginning exercisers be it female or male. You have to give credit where credit is due. The originator of this franchise recognized that there was a huge market for a gym such as Curves and surely has tapped into a goldmine.
GREAT CONCEPT, BUT WHAT ABOUT THE ACTUAL PROGRAM?
Curves is definitely great from a marketing and business perspective but what about
actual exercise program that is followed? One of
Curves members that I interviewed offered
following synopsis:
“They have about 10 different units. Leg extensions/leg curls, squats, leg press, glut press, biceps curls/triceps extensions, lat pull downs/overhead press, chest press/seated row, a dip/shrug machine, and a seated abdominal machine. They repeat some of
machines and you go around
circuit 1 and 1/2 times. In between each machine there is 3’ x 3’ platform that you perform some continuous exercise such as running in place or stationary jumping. The goal is to stay in
fat burning target heart rate zone for 30 minutes.”
Curves is a 30-minute exercise circuit comprised of hydraulic resistance machines and bodyweight exercises. The nature of
hydraulic machines used in
Curves program forces
user to perform concentric (muscle shortening) contractions of
opposing muscle groups. No eccentric (muscle lengthening) muscle action occurs when using these machines so very little muscle soreness is developed. The problem with
lack of
eccentric muscle actions is that it does not put a lot of stress on
muscle and a muscle not stressed is a muscle that will not change.
In fact, as Strength Coach Christian Thibeadeau points out in his book Theory and Application of Modern Strength and Power Methods,
“It was found that omitting eccentric stress in training program severely compromised
potential strength gains (Dudley et al. 1991). “ Curves members are encouraged to check their heart rates every 8 minutes to ensure that they are in their target heart rate zones. In summary,
Curves routine is a circuit-training program that focuses on muscular endurance and aerobic exercise.
A GOOD START BUT………..
It is important to point out that every exercise program has benefits and inherent weaknesses. I commend
originator of
Curves program for
benefit that it introduces women who would not otherwise be exercising to a regular exercise routine. There are, however, many limitations to
exercise routine utilized by Curves.
Some of those limitations are lack of an individualized exercise routine (cookie-cutter approach), absence of a comprehensive fitness assessment, reliance on limited-value hydraulic exercise equipment, lack of progressive overload (for both resistance training routine and cardiovascular conditioning), lack of exercise variety which can lead to overuse injuries, lack of program design that is based on current research to deliver optimal results, lack of instruction on how exercisers should progress after reaching a plateau with
program, and finally a lack of qualified supervision by an exercise specialist which poses many problems in itself. The lack of qualified supervision can lead to problems such as not knowing when to refer out to
appropriate medical professional if problems arise, recognizing when an individual is over-training, or modifying an exercise routine to suit
individual’s current needs and training level.
Simply put,
Curves fitness program utilizes outdated exercise programming that predisposes
exerciser to an abundance of overuse injuries (bursitis, tendonitis, medial and lateral epicondylitis, etc.) and does not deliver optimal results in
safest manner possible. I work full-time at a Physical Therapy clinic and we have seen countless cases of women developing overuse injuries from
Curves program. It should be a big red flag but some people just are not making
connection that
nature of
program is what causes
problems. I hate to say it and I hope that you are not offended, but
Curves program is fairly limited.
