Which of the following statements about maintaining a fitness program is true?
a.
progress is always steady.
b.
varying exercise types improve the likelihood of maintaining a program successfully.
c.
exercising with a partner can be fun, but does not improve the likelihood of maintaining a fitness program.
d.
starting off an exercise program at a high level of intensity is advisable to improve the chances of success.

B is the correct answer. Varying the type of exercise you do in an exercise programme improves the likelihood of maintaining the programme successfully because it avoids the programme becoming repetitive and dull. It also introduces benefits to different parts of the body. It allows you to work on some areas that you will naturally be better at, so you will be able to see your success in those areas rather than being disheartened by things you are less good at which will keep you committed.
