The talk test is used for monitoring exercise intensity.  The talk test means that if you can talk and sing while exercising without running out of breath, you're exercising at a low intensity. You don't need any equipment to do the talk test. A benefit of the talk test is that it is easy to perform. It is also reliable, practical, and inexpensive tool for monitoring exercise intensity.
