What is a hardgainer and why do they struggle to build muscle?
Ectomorph/Hardgainer somatotypes typically have long bones/limbs, narrow shoulders and little muscularity. Being a hardgainer or an ectomorph can be frustrating. They can be dedicated, spend hours upon hours pumping iron, but they have little to show for their efforts. They are the first in the gym and the last out, yet the casual gym-slackers are making bigger gains.
Although hardgainers usually find it hard to pack on mass, on the flip side they are very lean. It seems that no matter how much they eat they just cannot bulk up. The reason for this is because they tend to have lifestyle traits of being very active and snacking frequently. These two habits result in a high metabolism. Having a fast metabolism allows a person to burn a high number of calories at rest each day, making it more difficult to overeat than the average person.
