Find a program that matches your fitness level, or is staged to allow a start-up for beginners. Get a tape created by someone who seems to know a lot about exercise and fitness. Get the right shoes. Proper aerobic or cross-training footwear cushions your feet from impact, resulting in less chance of injury. Dress comfortably t-shirts and shorts or sweats will fit the bill.
Sweat is a good thing, prepare for it.
Keep a towel nearby when exercising. You should be drinking water before, during, and after a workout so keep it handy. Try to pick a time of day to exercise - make it a part of your routine. A muscle strain or other physical problem can make a trip to another room a long one. Monitor how you're feeling while exercising.
