Doctors and physiologists are concerned with how muscles use oxygen, digested food and nutrition supplements to produce energy, but for most of us aerobics are simple, easy and fun ways of staying fit.
The essential element of aerobics is to increase your heart rate through moderate exercise over an extended period. This means that sudden bursts of strenuous activity, such as in a quick sprint, do not qualify as aerobics. It is even more important however to train your heart and to build stamina in a series of steady and small steps. No one should start on a program of aerobics without a prior medical check. Your doctor can suggest a form and regimen of aerobics that will suit you best.
One of the reasons for the popularity of aerobics is that there are so many enjoyable variations of this form of fitness exercise that you never need to feel bored! Most people so look forward to their weekly aerobics sessions that they feel rather uneasy without the routine of stepping in time to the music. It is great for making friends as well.
Stamina, like the attentions of a person to who you are drawn, comes in small bits over time, but is quick to disappear! Do not try and catch up quickly with the most accomplished dancer or fitness freak in your group, and stick to the routine fixed especially for you by a trainer. Get down to your gym or track wherever else you have your work outs, as regularly as you can. Never forget to start over from scratch, if you have to take an extended break from your routine.
