Lunging into the weekend feeling accomplished... feeling accomplished because I know that I physically pushed myself this week. That is the only way to grow, you have to work hard.....then you must outwork your previous workout. You will feel tired, you will feel burned out, and pushing pass the pain is the only way way to reach the next level. Those who are able to so continue to seperate themselves from others who arent willing to endure the pain. . Lunges after doing 4 sets of 50 on the leg press machines leave your legs feeling like a truck hit them. My legs started growing the minute I lowered the weight and absolutely trashed them with maximum volume.
