How to warm up

Warm up right before you plan to start your workout. In general, warm up by focusing first on large muscle groups, such as the hamstrings. Then you can do exercises more specific to your sport or activity, if needed.

Start by doing the activity and movement patterns of your chosen exercise. But go at a low, slow pace that slowly builds in speed and intensity. This is called a dynamic warmup. A warmup may cause mild sweating. But a warmup generally won't leave you tired.

Here are some examples of warm-up activities:

• To warm up for a brisk walk, walk slowly for 5 to 10 minutes.
• To warm up for a run, walk briskly for 5 to 10 minutes.
• To warm up for swimming, swim slowly at first. Then pick up the speed as you're able.
