How to Gain Muscle Weight: A Practical Guide

Every body type is different

We're all different — some of us are tall, some naturally small, some breeze through their studies while others are just glad to finish school at all. The same goes for bodybuilding: our natural starting point depends on our body type. There are three basic somatotypes: ectomorph, mesomorph, and endomorph. Today we'll take a closer look at the first one, the ectomorph.

Most people start training to lose weight. The ectomorph has the opposite problem: they need (and often want) to gain it. This body type carries minimal body fat, but also minimal muscle mass. An ectomorph's metabolism runs fast, which is exactly why every extra pound of gain feels like a real win.

Nutrition

Ectomorphs often say they can eat as much as they want and still won't gain weight. The usual advice that follows is "just eat everything, all the time" — and that's simply not true. What matters isn't just how much you eat, but when and what. The single most important rule is that your calorie intake has to exceed your calorie expenditure. Skip that and you'll never gain. Aim for 2–3 g of protein per kg of bodyweight and plenty of complex carbohydrates.

Eat around five meals a day. Your metabolism already runs fast, so there's no need to speed it up further by eating small amounts more often. Breakfast should be your foundation — go heavy on complex carbs, oatmeal with milk is a great option, and don't be shy about the portion size. Say that's around 7 a.m. Lunch follows between 11 and noon: complex carbs again — rice, pasta — plus a solid dose of protein. Chicken works well, so does canned tuna in water or a piece of beef. Around 3 p.m., something like rice cakes with a protein shake works well. At 6 p.m., have something similar to lunch — rice or pasta with chicken, beef, tuna, or another fish. Then comes your last meal before bed, and this is where slow-digesting protein matters most: cottage cheese is a solid choice, or if your budget allows, a protein shake formulated for nighttime use (a "night protein").

Training for muscle weight gain

An ectomorph's training should center on the basics — bench press, squats, deadlifts, pull-ups, dips. Train these in a lower rep range, around 6–8 reps, with relatively heavy weight. Don't skip squats, and feel free to use higher reps for those specifically. Don't overdo the volume either — 6–8 sets per muscle group is plenty. As mentioned, calorie intake needs to exceed expenditure, which means if gaining weight is the priority, you should scale back other sports on top of your lifting. If you're a natural ectomorph who lifts but also plays football, swims, and cycles, gaining weight will be an uphill battle.

Supplements

Useful supplements here include: protein powder (always a solid choice regardless of body type), a carbohydrate drink (a gainer) — especially useful right after training — and creatine, which tends to be a reliable addition too.
