Don't be fooled by its seemingly harmless name, this quad killer can wreak absolute havoc on your thighs if done at the right time. After squats, leg presses and lunges, you can finish off your quads with this extreme stretching movement. Standing upright, slowly lower yourself toward the floor letting your pelvis and knees move forward. At the bottom of the movement, your butt should almost touch your heels. Hold the stretched position for at least five seconds, then straighten your legs, flexing your quads at the top. Repeat this stretching sequence for 10 reps.
If a patient asks about a specific ergogenic aid, he or she should be told what is known and unknown about the product based on current research, including the side effect profile. The danger is that once athletes start using a commercial supplement, they will continue to use more, eventually trying something that may not be safe. Many athletes feel pressured to use supplements to maintain a competitive advantage over their supplement-using peers. If physicians can guide athletes away from disproven and dangerous supplements, while maintaining open and honest lines of communication, then more serious health risks may be prevented.
