My new scale gives me a muscle mass percentage of 37.7 but I've no idea of what is a good % for my age/sex/height. Does anyone know of a muscle mass table that I can look up? I've googled it but I can't find one.

average for a female is 36% so you're right about on target. That's for the average of all adult females though, you guys can have 40 or 45% and be extremely healthy. More important is the Body Fat %. I.E. even if your muscle mass % is high, if your BF% is high as well, it means you could have less bone density than you'd want. For women, it's a good idea to have your bone density tested every few years as women can become highly susceptible to osteoporosis later in life, and the best time to catch and reverse that is when you are young. The next time you schedule a doctors visit, ask him if you can have your bone density tested.

since you are 30 Kate, this is a great time to have it done, as you are still at an age where you can easily build bone density through proper diet and weight training / resistance exercise. Once you get into your late 30's and early 40's it becomes far more difficult for the body to increase bone density (still possible, but it's far more difficult).

Thank you for your reply, my body fat is 25% which I believe is ijust inside the normal range for a woman of my age, although I'm working to reduce it a little. What is involved in a bone density test? I'm in the UK so I doubt its something I'd be able to have done on the NHS.

it's a laying down scan. Doesn't take that long. Most full medical facilities should be able to do it, I know the ones in the US do. It can also show any abnormalities in your bone structure. It's a good thing to have done every few years.

The average muscle mass is 36%?! I have the omron body composition scales with the handle bar and it measures "skeletal muscle" - is that the same as muscle mass? Because mine is only 31% but at the gym their toning leaflet said the average is 28% so Ithought I was ok? Lol if I should be at 36% then I have lots of work to do! huh

The more the better (to a point). different sources will have different amounts as the average. My sources list skeletal muscle mass averages for adult females as 36% (as a % of total mass), but depending on what yours takes as it's study group, it could be different. Maybe they go by a certain age group, or a certain demographic...etc. This can seriously alter the results. I'd say anyone with between 30 and 45% muscle mass (female) is probably doing ok. Men should be around 40 to 50% by the way. I have a nutrition college text at home that has the percentages, I can look that up when I get home from work. I don't remember off the top of my head, but that book is one of the "bibles" of human anatomy currently, so I generally trust it's facts. I'll post what I find later today.

FYI the numbers I got are from "Human Anatomy and Physiology" (7th edition) ISBN #: 0805353879

Can I jump here, as I've just got new scales too and am confused about the same thing. At first I thought it was giving me the muscle mass percentage (42.4), but I think that was the weight of my muscle mass in kilos; my total weight is 54.2 kilos. Is it really possible that so much of me is muscle??? I know I've been doing a lot of heavy lifting, but really!

Other interesting readings are 17.6% body fat (Eeek! Do I have to gain fat?) and visceral fat = 3 (1 - 12 is healthy).

Ideal Weight and Muscle Mass for Height
Comments May 26, 2011 | By Dana George Dana George has been a freelance writer since 2005, penning numerous articles, Web content and marketing collateral for both print and online. His articles have appeared in "Healthy Knowledge" magazine, "Minneapolis Metro Mix" and "Meefers." George holds a Bachelor of Arts from the University of Wisconsin.
Your ideal body weight can be roughly estimated based on your height and body frame size. Muscle mass, on the other hand, isn't as easily determined, especially when referring to an ideal. Muscle mass isn't a good indicator of health, so it's better to look at your body fat percentage or waist circumference to determine your risk of certain health complications.

Body Weight
The National Institutes of Health provides a rough estimate of desirable body weight for height. Women should weigh approximately 100 lbs. at 5 feet and then another 5 lbs. for each inch over this height. Men should weigh a bit more, coming in at 106 lbs. at 5 feet and then an extra 6 lbs. for each inch over this height. This means at a height of 5 feet 10 inches tall, a female should weigh around 150 lbs., whereas a male should weigh 166 lbs.

Body Frame
This calculation, however, doesn't account for differences in body frame size. Small frames deduct 10 percent from this desirable weight, while 10 percent is added for large frames. Females have a small frame with a wrist of less than 5 ½ inches at a height of under 5-foot-2, less than 6 inches at a height between 5-foot-2 and 5-foot-5 and less that 6 ¼ at a height over 5-foot-5. Women have a large frame when wrist size is greater than 5 ¾ at a height of under 5-foot-2, greater than 6 ¼ inches at a height between 5-foot-2 and 5-foot-5 and less that 6 ½ at a height over 5-foot-5. A small frame for men is usually a wrist size of less than 6 ½ inches and a large frame is a measurement over 7 ½.

Muscle Mass
Unlike weight, muscle mass doesn't have a so-called ideal based on your height or even body frame size. In fact, muscle mass varies greatly from person to person, based largely on physical activity. Instead of focusing on muscle itself, most medical professionals defer to body fat to determine if your muscle mass is at an ideal percentage for your height. Women should have a body fat percentage somewhere between 20 and 21 percent. Men should have far less, coming in at 13 to 17 percent. Talk to a doctor or physiologist to determine this percentage.

Fat Distribution
Besides body weight and body fat percentage, it's also important to look at your distribution of body fat, explains the National Institute of Diabetes and Digestive and Kidney Diseases. It's especially problematic for people to carry excess fat around their midsection. When women have a waist circumference over 35 inches, it places them at a greater risk of developing high blood pressure, high blood cholesterol, heart disease and type 2 diabetes. For men, these risks increase with a waistline of over 40 inches

my fat percentage is higher than my muscle. I am just wondering what types of excersize i could do in the house to help me. The gym is too expensive

This is so weird. My visceral fat is 2, and my muscle mass is 42.3, yet my body fat is 30.4%. So I guess the first two values are good, but I really need to lose some body fat! We're all built differently I guess.
