How to build muscle fast for skinny guys: ultimate guide

💪 I Gained 50kg of Muscle as a Skinny Guy: Here’s the Exact Plan I Used

If you’re a skinny guy struggling to gain weight and wondering if it’s even possible to pack on serious muscle — I get it. I’ve been there.

I started out with fast metabolism, small appetite, and no clue what I was doing. But through years of trial and error, I gained 50kg of lean muscle — and in this article, I’m giving you the exact plan I used to make it happen.

This isn’t some generic fitness blog post. This is the real deal — what actually worked for me. And it’s the same approach we’ve built our website on: honest advice for skinny beginners, backed by real transformation and tested supplements.


🔑 My Muscle-Building Foundation: workouts, Food, Supplements

🏋️‍♂️ My Muscle-Building Training Plan: Simple, Effective, and Consistent

I didn’t follow complicated splits or track every number in a training app. What worked for me was simplicity, consistency, and pushing myself hard in every session.

Here’s how I structured my training early on:

🗓️ Phase 1: My Original Weekly Split

  • Monday: Back

  • Tuesday: Legs & Calves

  • Wednesday: Chest & Biceps

  • Thursday: Rest

  • Friday: Shoulders & Triceps

  • Saturday: Legs

  • Sunday: Rest

After some time, I adjusted to a slightly different approach, keeping it just as straightforward:

🗓️ Phase 2: What I Switched To

  • Monday: Chest

  • Tuesday: Back

  • Wednesday: Arms

  • Thursday: Shoulders

  • Friday: Legs

  • Saturday & Sunday: Rest

No push/pull splits. No upper/lower. Just real training, consistent effort, and recovery.

👊 My Philosophy on Progression

Of course, progressive overload is key to building muscle — but I didn’t obsess over numbers every week. I didn’t track every rep or anything like that. I used two simple tools:

  • The mirror

  • The scales

If I was getting bigger, stronger, and looking better — it was working.

Some weeks, you’re tired. Life gets in the way. You’ve been working all day. Expecting to always beat your last session is unrealistic. What matters most is this:

  • Show up

  • Train hard

  • Use proper form

  • Push to failure

If you do that consistently — the gains will come.

🥩 My Skinny Guy Diet Plan That Actually Worked

When you’re naturally skinny, it takes a lot more food than you think to build serious muscle. I had to eat even when I wasn’t hungry. Here’s what worked for me 👇

🔥 Skinny Guy Muscle-Building Diet Plan

Meal 1: Breakfast (7:00 AM)

  • Amino drink (first thing)

  • Bowl of Cheerios

  • 4 Weetabix Protein

  • 2 Greek yogurts

  • Half Serving of Mass Gainer Shake

Meal 2: Morning Snack (10:00 AM)

  • 2 Greek yogurts + granola

  • Ham & cheese sandwich and 2 crumpets

  • Whey Protein shake

  • (Optional: Chocolate bar or doughnuts)

Meal 3: Lunch (1:00 PM)

  • Baked potato with tuna & butter

  • Whey Protein shake

  • (Optional: Another chocolate bar)

Meal 4: Pre-Workout Snack (5:00 PM)

  • 3 scrambled eggs

  • Porridge or 4 Weetabix Protein

  • Protein bar

Workout (5:30 PM)

  • I drank a mass gainer shake 30 minutes before training and Creatine + amino acids as I was working out

Meal 5: Dinner (7:00 PM)

  • Quarter-pound burger + chips

  • 1 chicken breast

Meal 6: Before Bed (9:00 PM)

  • 2 scrambled eggs

  • 1 bowl of porridge

  • Whey protein shake before bed

👉 This plan was high-calorie and high-protein — exactly what a skinny guy with a fast metabolism needs. You can adjust portions based on your appetite and goals and as your weight increases.


🔬 What Supplements I Used (and When)

Supplements didn’t replace my meals — they enhanced them. Here’s what I consistently used:

  • Mass Gainer Shake (before gym, half serving with breakfast, sometimes post-gym)

  • Whey Protein (midday and before bed)

  • USN Muscle Fuel Anabolic (used this during leaner bulk phases for slow, clean growth)

  • Mutant Mass Extreme (used during full-force bulk phases)

  • Creatine – always added it, even when my shake already had some (especially USN Muscle Fuel) The ones i used was a micronised creatine and the usn creatine anabolic was really good. 

  • Amino Acids – first thing in the morning and around workouts


⚠️ What I Wish I Knew at the Start

  • You have to eat more than feels “comfortable” — that’s the point

  • Supplements help — but only if your food is right first

  • Stick to the basics — you don’t need 20 exercises per session

  • Track your weight weekly and adjust your food if you’re not gaining


💭 Final Words: You Can Do This

Gaining 50kg wasn’t easy. It took consistency, food, rest, and knowing when to go all in. But it was 100% worth it — and now I help others do the same.
