Short Warm-Ups May Be Best
A study by the University of Calgary Human Performance Laboratory found that certain types of warm-up activities may be better than others when it comes to improving performance, and delaying fatigue. Their research showed that shorter, less intense warm-ups may be better than long, more intense warm-ups.
The Centers for Disease Control and Prevention, for example, recommends a 5 to 10-minute walk to warm and loosen your muscles before moving into a strength-training session.
A warm-up session prior to a workout is essential to prevent injuries.
Cold muscles do not stretch and contract as readily as when their fibers are warm. Consequently, tearing may occur if you skip the warm-up. In addition, a warm body’s capacity to deliver oxygen and nutrient-loaded blood to muscle tissue is greater.
Before you start your strength-training with proper weights, you should do one warm-up set with easy weights on every muscle-group you train.
