Cardiovascular endurance is the most important component of physical fitness. There are two
types of cardiovascular training, these are interval training and steady state training.
Interval training varies the amount of effort required to workout. The LifeSpan TR2250 comes
with 6 programs that vary incline automatically and 6 programs that vary speed. All of these
programs vary the amount of effort required during the workout either through automatically
adjusting the incline or the speed.
Steady state training keeps the workload constant. The Manual program on your LifeSpan
treadmill allows you to manually control the speed and incline of your treadmill providing you
with a constant workout that you completely control. The TR2250 models also support Heart
Rate training where you can preset the treadmill to a target heart rate. On the TR2250-HR the
treadmill will need to pick up your heart rate through the grip pulse sensors located on the
handlebars, while the TR2250-HRC has a built in receiver that picks up your heart rate while
using a heart rate chest strap. The treadmill will then automatically adjust the speed to
maintain your target heart rate.
If you have a requirement to maintain a steady heart rate during your workout, the manual or
Target Heart Rate Program is the best selection.
Regardless of your personal fitness goals and the program that you pursue, warming up and
cooling down before and after you workout will help reduce the risk of injury and improve the
effectiveness of your workout.
Warming up is important to bring your body from its normal level of activity to a state where it is
ready to exercise by increasing the flow of blood to the muscle to raise the muscle
temperature. This will increase the muscle elasticity and protect the joints. The warm up
period also helps to mentally prepare you for your workout.
Warmups should be done at a low intensity level and last for at least five minutes.
Cooling down after your workout is required to gradually bring your cardiovascular system down
to its normal level.
Follow your workout with at least 10 minutes of stretching. Focus on the major muscle
groups of the lower extremity. When stretching, stretch the muscle until you feel gentle
tension, hold it and wait for the tension to relax while the muscle elongates, stretch the
muscle again until you feel gentle tension.
Do not bounce when you stretch, bouncing is not an effective approach to stretching and can
lead to injury.
