Weight lifting and cardio needn’t be dangerous. Proper form is the single most important factor in injury prevention. Correct posture when working out is as or more important then the exercises you are performing. Stand straight, look forward keep your abs tight and keep your knees over your second toe. When viewed from the side your ears should not be in front of your shoulders nor your shoulders be in front of your chest, if so your body is out of alignment and you could possibly be setting yourself up for injury. Always bend your knees when bending forward to lift any weight or perform any type of calisthenics. Remember to keep your feet apart to give yourself a strong base of support. Keep any weight you are lifting close to your body to minimize stress on you lower back. Following these simple techniques will enable you to get the most out of any exercise and prevent injury and setback in your exercise routine.
