PEOPLE WILL OFTEN ASK ME, “IS THERE SUCH A THING AS AN EXERCISE RUT?” THEY WANT TO KNOW WHY THEY DO NOT SEEM TO BE IMPROVING WITH THEIR EXERCISE PROGRAM…they exercise 3-4 times a week for 30 to 45 minutes and they feel frustrated and STUCK in a rut. While initially responding favorably to exercise, after 6 -9 months or more, they do not notice progress in weight loss, strength, tone, endurance or daily function.

The purpose of this column will be to offer suggestions on how to improve or get more out of a “stale” exercise program or an exercise rut. Step one is to build an exercise program that is grounded in the basics. Next step two, which begins after the basics have been mastered, includes the components necessary for a healthy mind, body and spirit connection and translates into functional activities of daily living including work and leisure sports.

STEP ONE: CARDIOVASCULAR; STRENGTH; FLEXIBILITY

Make sure your routine has all three fundamental components of a well-balanced exercise program; cardiovascular, strength and flexibility training. While each component offers its own specific benefit, the combination of all three cooperatively provides unique value. Too often, fitness enthusiasts concentrate on the exercises they LIKE or are good at more than the ones they NEED. A well-balanced program includes what you like and need! In fact, recent studies show that those performing all three components surpassed those performing one or any combination of two of the training types when tested for efficient oxygen uptake (VO2 Max), production of HDL (good cholesterol), lower body fat percentage, and lower blood glucose levels.

CARDIOVASCULAR TRAINING:

Cardiovascular exercise is any activity that raises your heart rate and respiratory rate. This type of exercise strengthens the heart muscle and the muscles that assist in breathing. When these muscles are stronger, they in turn work more efficiently to deliver oxygen to your muscles and other parts of the body. Ultimately, these oxygenated muscles can work harder and longer to burn fat during exercise and at rest.

Examples of Cardiovascular Exercises:  Running, Brisk Walking, Swimming, Biking, Rowing, Elliptical Training and Stepper Training. Most experts recommend at least 30 minutes of sustained cardio, 3-4 days per week. However, recent studies support the notion of performing 10-15 minutes, twice daily, 4 days per week. For those “stuck” in a fitness or exercise rut, to advance your program, cardio should be performed 5-6 days per week for 45-60 minutes.

Improving a Cardio Training Program:

• Alternate Types of Cardio: run walk one day, bike the next, and use the stepper or elliptical a third day.
• Alternate Direction: when using equipment that allows changing direction such as the elliptical or treadmill, go forward for 5 -10 minutes then backwards for 3-5 minutes, even if you have to slow the speed down.
• Alternate Intensity: interval training for cardio can be invaluable to improve benefits. Interval training includes performing 1, 2 or 3 minute bursts of high intensity cardio followed by a 2 or 3 minute recovery at a slower speed and lower resistance. 15 to 20 minute intervals should always begin with a warm-up and end with a cool down.

STRENGTH TRAINING:

Strength training is an activity that provides any type of resistance to muscle contraction to build strength in the muscle. The resistance can be without movement against an immovable object such as pushing against a wall (isometric) or with movement such as lifting up or lowering a weight down against gravity (isotonic/dynamic). There are two types of isotonic muscle contraction; concentric, which involves raising the weight against gravity as the muscle shortens and eccentric which involves lowering a weight against gravity as the muscle lengthens. A standing biceps curl is an example that incorporates both concentric and eccentric contractions. A progressive strength training program includes all three types of muscle contraction. By using the classic bicep muscle curl these photos will demonstrate all three types of muscle contraction:

-Isometric Bicep Muscle Curl – pull up on door knob without allowing any movement of the arm.

-Concentric Bicep Muscle Curl – raise a dumbbell up against gravity as the muscle shortens.

-Eccentric Bicep Muscle Curl – lower a dumbbell slowly (4-6 seconds) against gravity as the muscle lengthens.

Improving a Strength Training Program:

• Incorporate the use of all three types of muscular contractions in the program. Perform one set of exercises using isometrics as a warm up followed by a typical weight training program. Then, consider performing one set using only eccentrics (lowering the weight). To do so, a training partner may be necessary to help lift the weight up before it is lowered eccentrically.
• Vary the Weight: warm up with lighter weight and gradually progress.
• Vary the Speed: one day lift and lower to a 10 count and the next increase the speed to a 2 count – even if requires using a lower weight.
• Vary the Types of Resistance. Mix up the routine with exercise bands, dumbbells, weight lifting machines and weighted balls. Also, incorporate using the weight of your body (push ups, planks, lunges).
• Vary Body Parts. One day exercise the upper body and the next the lower body. Include core exercises for both.
