6 mistakes that sabotage your workout

Simple mistakes can undermine an exercise regimen. Some errors can lead to muscle injury, such as skipping a warm-up before a workout, slouching while exercising, cramming too much into a single exercise session, lifting too much weight, and working the same muscle groups every day without allowing them to rest properly. Another big mistake is not staying properly hydrated, which can be tough on the heart and muscles. To avoid mistakes, it might help to work with a physical therapist or personal trainer.
