Endomorph: Sturdy and Big Boned

An endomorph has large bone structure, a wide waist, and stores fat well. Round curves through-out the whole body; Rubenesque.

Weight training is one of the best methods of strength training! If you want to start weight training safely and effectively, with the best info, diet, and routines, check out the 5 Day Beginner Weight Training Course!

Endo's are one of William Sheldon's three somatotypes. The other two are mesomorph and ectomorph.

Textbook Characteristics Of Mesomorphs

An endomorph is big boned and puts on fat easily.
  • Wide waist and hips, narrow shoulders.[1]
  • Low level of motivation; relaxed disposition.[2][3]
  • Large bone structure.
  • Strong lower body.[4]
  • Gains weight, especially fat, easily.

More (Supposed) Info About Endo's

Endo's have a higher body fat to muscle mass ratio.[5] This has to do with the build of your body, as well as the fact that endo's tend to have slow metabolisms.[6]

The fat tends to collect on your abs, butt, hips, and thighs.[7] Spot removal of fat (i.e. doing crunches to burn ab fat) doesn't work, so just make sure to do aerobic exercise or weight lifting to stay healthy.

But, endo's have very strong lower bodies! If you're lifting weights, you'll probably do very well on squats, deadlifts, and other exercises that benefit from lower body strength.[8]

One thing to keep in mind is that people are rarely pure endo, ecto, or mesomorph. You are most likely a mix of the three somatotypes.

But, Don't Trust Your Body Type!

Above are listed all the classical attributes of endomorphic body type people.

But your body type is not set in stone.

The American psychologist William Sheldon's three body type classification of people was developed in the 1940s and 50s. He was a psychologist, not a doctor, and I have issues with his sampling techniques.

NOTE: His subjects were all entering freshmen at Ivy League collages (not representative of the general population). Also, he assigned personality types to people based on their body type - A COMPLETE LOAD OF BOLLOCKS!

If you're an endomorph, the 'endo' term is fine as a educated way of saying, "Yea, I have a strong lower body and put on fat easily." But you are not sentenced to being an endo by genetics or the whims of fate!!!

If you watch your diet and workout, there's no reason you can't get muscular and ripped!

"About 2 weeks ago I read all the ab strengthening stuff on your site because I decided I wanted to be strong, instead of having a lot of belly fat. So I started eating healthier, running, exercising, you name it - everything your site said to do to help. Now I am noticing a real difference! Thank you for making this. :D xD"

[This calorie calculator is] the most useful tool on the web that I can find… Also, I compared the calories calculated by your calculator to the calories calculated by the treadmill at my gym, and they're within a couple calories of each other, so yours is as accurate as we're going to get. REALLY AWESOME TOOL. I love it and depend on it. Thank you sooooo much for making this available."

Thank you very much, I was too lean before 2 years (55 Kgs), after the gym now I'm 72kgs, all the muscles have developed... when someone hand shakes with me it can be squeezed easily, they're making fun of me!
