ACE Fitness OVERWEIGHT & OBESITY OVERWEIGHT & OBESITY What are the guidelines for percentage of body fat loss? FILTER BY CATEGORY  Natalie Digate Muthby Natalie Digate Muth on December 02, 2009 Body fat testWith the New Year upon us, millions of people are thinking hard about their New Year’s resolutions, many of which will likely include ambitious nutrition and fitness goals. Given the increasing ease of measuring body composition and the known benefits of decreasing body fat percentage, it is no surprise that fitness professionals and consumers alike want to know how much body fat they should expect to lose. Unlike the well-researched and accepted guideline that an individual should lose no more than 1-2 pounds per week, body fat percentage loss is not as well studied and no official guidelines have been published. Still, most experts agree that a 1% loss per month is generally safe and doable. However, it is important to recognize that most methods of measuring body f...

Is it safe to be working out while sore?  The answer to this question depends on the severity of muscle soreness, which can range from slight tenderness to debilitating pain. Delayed onset muscle soreness (DOMS) happens 1-2 days after exercise. The most likely cause of DOMS is microscopic muscle tears or a breakdown in muscle tissue that occurs during a workout. Introducing new activities or suddenly increasing the intensity can cause DOMS to occur. During periods of severe muscle soreness, a person has impaired coordination, less shock absorption, and a shortened range of motion. If you exercise while very sore you are likely to alter your body mechanics putting more stress on ligaments and tendons and therefore increasing your risk of injury. Should You Work out When You are Sore? Overreaching is the state of training intensely without rest. This leads to overtraining and a decline in athletic performance. It takes several weeks to months for this condition to occur, but watch fo...

is correct to avoid excessive forward movement of the knee during squatting and lunging movements. It is a myth, however, that you should “never let your knees go past your toes while doing a squat or lunge." This belief originated from a study that is more than 30 years old (1978 Duke University study that found maintaining a vertical lower leg as much as possible reduced shearing forces on the knee during a squat). The truth is that leaning forward too much is more likely what is truly causing the problem or injury. Read on for more information regarding these functional movement exercises and how to have correct form. In 2003, University of Memphis research confirmed that knee stress increased by 28% when the knees were allowed to move past the toes while performing a squat. However, hip stress increased nearly 1,000% when forward movement of the knee was restricted. In addition, in group exercise, the cue “don’t let your knees go over your toes” has long been an effective gene...
