Ectomorph Workout Plan: Beginner Weight Training Routine

Skinny guys are often called “ectomorphs.” It’s a slang term referring to our thinner bones, narrower frames, shallower ribcages, or lankier limbs. Does being naturally thinner affect how we should exercise, lift weights, and build muscle?

Many of us ectomorphs also have atypical goals. Most people want to lose weight, we want to gain it. Most people intuitively eat too much food, we eat too little. We’re usually eager to bulk up, and we often have a hard time of it. Some may even worry they’ve got bad muscle-building genetics. Does that change how we should train?

Different workout programs are designed for people with different goals. Some, like CrossFit, are designed to improve our general fitness. Others, like Starting Strength and StrongLifts 5×5, are designed to improve our general strength. Still others, such as bodybuilding, seem entirely centred around helping naturally muscular guys gain even more muscle. What’s the best way to work out if we’re trying to gain muscle size?

So, how should ectomorphs work out?
