RESISTANCE TRAINING BENEFITS AND TIPS
Always consult a physician before starting an exercise program.
To be successful in your exercise program, it is important to develop an understanding of the basic principles of
resistance training. Now that you have assembled your VISION FITNESS gym, it is only natural that you want to
get started immediately. First, determine a few realistic, short term goals and expectations for yourself. Choose an
appropriate exercise routine that best suits your individual needs. Any of the 3 programs, explained in the Training
Programs section below, is a great starting point.
Warm up properly before engaging in resistance training. Stretching, yoga, jogging, calisthenics, or other cardiovascular
exercise can help prepare your body for the heavier workload of lifting weights.
Learn how to perform the exercise correctly before using heavy weight. Correct form is important to avoid injury
and ensure that you work the proper muscle groups.
Know your limitations. If you are new to resistance training or are starting back, after an extended layoff, start slowly
and build foundational strength over a longer period of time.
Pay attention to your breathing. As a general rule of thumb: inhale on the non-exertion part of the movement and
exhale during the exertion portion. Never hold your breath.
Keep in mind how important the recovery phase is in achieving your goals. The general rule is to allow a minimum
of 48-72 hours before training the same muscle/s. If you still experience soreness after this period of time has
elapsed, take a few additional days until the soreness has subsided.
Use this manual to guide you through the basic exercises you can perform on your VISION FITNESS gym. To achieve
maximum results and avoid possible injury, consult a fitness professional to formulate a complete exercise program.

TRAINING PROGRAMS
MUSCULAR ENDURANCE
A program that stresses moderate intensity, a lower amount of resistance, and higher repetitions (anywhere from
13-100 or more). These types of sets will take longer to complete. This type of training conditions the muscles for
activities that stress the slow twitch muscle fibers of your body. This is beneficial for sustaining energy over moderate
periods of time.
MUSCULAR STRENGTH
A program that stresses high intensity, a higher amount of resistance, and lower repetitions (anywhere from 6-12).
These types of sets will take a shorter period of time to complete. This type of training conditions the muscles for
activities that stress the fast twitch muscle fibers of the body. This is beneficial for activities that require short bursts
of speed and power.
SPRINT 8
This program is exclusive to VISION FITNESS exercise equipment. This is a program that stresses high intensity, a
moderate amount of resistance, and as many repetitions that a person can perform in a specified period of time
(usually 20-30 seconds). This program works especially well for the time crunched exerciser. It allows you to work
both the slow and fast twitch muscle fibers of the body. This program gives you a good cardiovascular and strength
workout. The thing that is most appealing about this program is that an individual can complete it in 20 minutes.
This is how the program works:
The person picks the number of exercises they want to perform. Examples would be 1, 2, 4, or 8 exercises. The
individual completes a 3 minute warm up with a brisk walk or on a piece of cardiovascular equipment. After the
warm up is complete, the user begins performing the first exercise maintaining a high intensity pace throughout the
determined amount of time (20-30 seconds). After this period of time, the individual can perform an active, low
intensity recovery phase, stretching, or complete rest. This should last 1.5-2 minutes or less, if you are at a higher
fitness level. After the recovery phase, the individual performs the second high intensity exercise for the required
amount of time (20-30 seconds). This is followed by the second recovery phase. This process repeats until you are
done with 8 high intensity intervals. Finish the workout by completing a 3-5 minute very low intensity cool down.

STRETCHING
Flexibility Training is not associated with fitness as often as cardiovascular exercise or Strength Training, even
though it is just as important. A good stretching program will help to maintain flexibility of the hips and lower
back. A flexible person will be less likely to injure themselves in common activities, such as reaching, twisting and
turning, or in uncommon activities such as the annual softball tournament.
Before stretching, take a few minutes to warm up the muscles because stretching a cold muscle can cause injury.
Start your stretch slowly, exhaling as you gently stretch the muscle. Try to hold each stretch 15 to 30 seconds.
Don’t bounce when you stretch. Holding a stretch offers less chance of injury. Don’t strain or push a muscle too
far. If it hurts, ease up. Here are a few stretches you can incorporate into your exercise program:
SEATED TOE TOUCH
(HAMSTRINGS & LOWER BACK)
Sit on the floor with your legs together and straight out in front of you. Do
not lock your knees. Extend your fingers toward your toes, exhaling as you
go. Hold for 15 to 30 seconds. Return to the start position, and repeat as
necessary.
STANDING QUADRICEPS STRETCH
Using a wall to provide balance, grasp your left ankle with your left hand
and hold to stretch. Your knee should be pointing toward the floor. Hold
the stretch for 15 to 30 seconds. Repeat with your right leg, and continue
to alternate as necessary.
STANDING CALF STRETCH
Standing about three to four feet from the wall, take one step forward with
your right foot. Place your hands on the wall in front of you. Bend your right
leg slowly, using your movement to control the amount of stretch in the left
calf. Your left heel should remain on the ground. Slowly bring yourself back
to the starting position and switch legs. Repeat as necessary.

BICEP/CHEST STRETCH
Grasp an immovable object (pole or corner of a wall) with your feet
planted firmly and evenly on the floor. With the palm of your stretched side
facing forward, rotate your hips away from that hand. Be careful not to rotate
too far or hyperextend the elbow joint. Hold the stretch for 15 to 30 seconds. Repeat
with the opposite side, and continue to alternate as necessary.
TRICEP STRETCH
Stand erect with your eyes fixated straight ahead. Raise and bend your
right arm until your forearm is parallel to the floor (palm down). Grasp the
area below the right elbow with your left hand. Gently apply a constant
upward force for 15 to 30 seconds. Switch arms and repeat as necessary.
SHOULDER STRETCH
Make sure your feet are even and planted firmly on the floor. Grasp your
right arm, behind the elbow, with your left hand. While keeping both
elbows bent, apply a gentle, constant pull to the left for 15 to 30 seconds.
Switch arms and repeat as necessary.
UPPER BACK STRETCH
Stand facing an immovable object, feet even and flat on the floor. Grasp
the object (fingers interlocked or one hand over the other) and slowly move
your hips to the rear. Be very careful not to round your back. Only stretch as far as
your comfort zone. Hold for 15 to 30 seconds and repeat as necessary.
