While performing situps or crunches, push your tongue against the top of your mouth. By holding your tongue like this, it engages your neck muscles and keeps them aligned properly. Not only will you reduce the risk of muscle strain, but you also will avoid injury as well.
Be sure to do barbell squats when you are exercising if you desire a more muscular build. Squats are a great way to build up your core muscles and add to your overall mass.
Make sure to loosen up your muscles before you engage in weight lifting. Stretching the muscle you are going to lift should be standard practice for everybody. If you are under 40, a 30 second stretch is adequate. However, if you are over 40, then you may want to stretch longer.
