Take five to 10 minutes to warm up and cool down properly.
If you stop exercising for a while, drop back to a lower level of exercise initially. If you’re doing strength training, for example, lift lighter weights or do fewer reps or sets.
Choose clothes and shoes designed for your type of exercise. Replace shoes every six months as cushioning wears out.
For strength training, good form is essential. Initially use no weight, or very light weights, when learning the exercises. Never sacrifice good form by hurrying to finish reps or sets, or struggling to lift heavier weights.
Dress properly for cold-weather workouts to avoid hypothermia. Depending on the temperature, wear layers you can peel off as you warm up. Don’t forget gloves.
