The Truth About Building Muscle (No BS)
You cannot build muscle without:
- A calorie surplus β you need to eat more than you burn. A modest 250β500 cal surplus minimises fat gain.
- Enough protein β 1.6β2.2g per kg bodyweight daily. For an 80 kg person, that's 128β176g protein per day.
- Progressive overload in the gym β you must lift heavier or do more reps over time. No amount of food builds muscle without this stimulus.
That's it. Supplements help at the margins. The three points above are 95% of the result.
How Many Calories to Eat to Gain Muscle
Use this table to find your starting calorie target. Adjust by 100 cal after 2 weeks if not gaining:
| Bodyweight | Sedentary + training 3x/wk | Active + training 4β5x/wk | Very active athlete |
|---|---|---|---|
| 60 kg | 2,200β2,400 cal | 2,500β2,700 cal | 2,800β3,100 cal |
| 70 kg | 2,500β2,700 cal | 2,800β3,100 cal | 3,200β3,500 cal |
| 80 kg | 2,800β3,000 cal | 3,200β3,500 cal | 3,600β3,900 cal |
| 90 kg | 3,100β3,300 cal | 3,600β3,900 cal | 4,000β4,300 cal |
| 100 kg | 3,400β3,700 cal | 4,000β4,300 cal | 4,400β4,700 cal |
Protein β The Most Important Macro for Muscle
Aim for your protein target FIRST. Fill remaining calories with carbs and fats. Best NZ protein sources:
| Food | Protein per 100g | Cost (NZ) | Best For |
|---|---|---|---|
| Chicken breast | 31g | $8β12/kg | Daily staple, very lean |
| Eggs (2 large) | 12g | $0.80β1.20 | Breakfast, snacks |
| Greek yoghurt | 10g | $4β7/500g | Snacks, post-workout |
| Canned tuna | 25g | $1.50β3/can | Lunch, cheap, convenient |
| Lean beef mince | 21g | $9β14/kg | Dinner meals, iron |
| Salmon fillet | 25g | $14β22/kg | Omega-3s + protein |
| Cottage cheese | 11g | $3β5/250g | Slow-digesting protein (casein) |
| Whey protein | 70β80g/100g | $25β50/kg | Convenient after gym |
| Tofu (firm) | 8g | $3β5/300g | Plant-based option |
| Lentils (cooked) | 9g | $1.50β2/can | Cheap plant protein + carbs |
Sample 7-Day Muscle-Building Meal Plan
Targeting ~2,800 calories and 170g protein/day (for an 80 kg person training 4x/week). Scale portions up or down.
| Day | Breakfast | Lunch | Dinner | Snacks |
|---|---|---|---|---|
| Mon | 3 eggs + oats + banana | Chicken wrap x2 + salad | Beef stir-fry + rice + veges | Protein shake + apple |
| Tue | Greek yoghurt + granola + berries | Tuna salad + 2 slices grain bread | Salmon + kumara + broccoli | Cottage cheese + nuts |
| Wed | Protein smoothie (2 scoops + oats + milk) | Chicken & rice bowl + slaw | Lamb mince bolognese + pasta | 2 boiled eggs + fruit |
| Thu | Omelette (3 eggs + veges + cheese) | Leftover bolognese + bread | Chicken thighs + roasted veges | Protein shake + banana |
| Fri | Overnight oats + protein + chia seeds | Chicken wrap + yoghurt | Lean beef burger (wholegrain bun + salad) | Almonds + Greek yoghurt |
| Sat | Big brekky: eggs, toast, tomatoes, mushrooms, bacon | Chicken fried rice | Barramundi + salad + potato | Protein shake |
| Sun | Pancakes (protein recipe) | Roast chicken + veges + gravy | Chickpea curry + naan + rice | Cottage cheese + berries |
Timing Your Nutrition Around Training
Timing matters less than total daily intake β but these habits help optimise muscle growth:
- π Pre-workout (1β2 hrs before): Carbs + moderate protein. Example: banana + Greek yoghurt, or rice + chicken.
- β‘ Post-workout (within 2 hrs): 30β40g protein + carbs. Example: protein shake + banana, or chicken + rice.
- π€ Before bed: Casein protein (cottage cheese, Greek yoghurt) β slow-release protein feeds muscles overnight.
- β° Spread protein across meals: 4β5 meals with 30β40g protein each maximises muscle protein synthesis.
- β Pre-workout coffee: 200mg caffeine 30β60 min before training improves strength by 3β5% on average.
The Muscle-Building Training Plan (3 days/week minimum)
Nutrition feeds muscle β but you still need to lift. Here's a simple, proven beginner programme:
| Day | Workout | Key Exercises | Sets Γ Reps |
|---|---|---|---|
| Day A (e.g. Mon) | Push | Bench press, shoulder press, tricep dips | 3β4 Γ 8β12 |
| Day B (e.g. Wed) | Pull | Pull-ups/lat pulldown, rows, bicep curls | 3β4 Γ 8β12 |
| Day C (e.g. Fri) | Legs + Core | Squats, deadlifts, lunges, plank | 3β4 Γ 8β12 |
Supplements Worth Taking for Muscle Gain
Most supplements are unnecessary if your diet is right. These three have the best evidence:
- πͺ Creatine monohydrate β The most studied supplement in sports science. Increases strength 5β15%, accelerates muscle growth. Take 3β5g daily. Cost: ~$20β40/month at Chemist Warehouse NZ.
- π₯ Whey protein powder β Not magic, just convenient protein. Use to hit your daily protein target when food alone isn't enough. Cost: ~$30β60/kg. Pak'nSave often has the best prices.
- β Caffeine (coffee or supplement) β Proven performance enhancer. 200mg pre-workout improves reps, reduces fatigue. Cheapest as instant coffee β $5β10/month.
Common Muscle-Gain Mistakes in NZ
- Not eating enough β most beginners eat at maintenance and wonder why they're not growing. Track for 2 weeks to check.
- Too much cardio β marathon training burns the calories you need for muscle. Keep cardio to 2β3 moderate sessions/week max.
- Changing programmes every 4 weeks β trust a simple programme for 12β16 weeks. Results require consistency.
- Skipping legs β lower body muscles are the biggest in the body. Squats and deadlifts raise testosterone and grow muscle everywhere.
- Underestimating sleep β 90% of muscle repair happens during sleep. 7β9 hours is not optional for muscle gain.
- Only using machines β free weights (barbell, dumbbells) activate more muscle fibres and build more functional strength.
