Full bio →Rucking is walking with a weighted pack. No special fitness required, no gym membership, no running shoes. You need a backpack, something heavy to put in it, and a route. This guide covers everything a beginner needs to start safely and build up to meaningful calorie burns.
Choosing Your Starting Weight
Rule of thumb: start with 10% of your bodyweight.
| Your weight | Starting pack weight |
|---|---|
| 60 kg (132 lb) | 6 kg (13 lb) |
| 70 kg (154 lb) | 7 kg (15 lb) |
| 80 kg (176 lb) | 8 kg (18 lb) |
| 90 kg (198 lb) | 9 kg (20 lb) |
| 100 kg (220 lb) | 10 kg (22 lb) |
If you have no current exercise habit, start at 5% of bodyweight for the first 2 weeks. Your tendons and lower back need more adaptation time than your cardiovascular system.
The goal for your first ruck: finish feeling like you could have gone longer. Starting too heavy is the #1 cause of early injury and dropout.
How to Increase Weight Over Time
Add weight gradually — 2.5 kg every 2–3 weeks maximum. Most beginners reach a productive training weight of 15–20% of bodyweight (12–16 kg for an 80 kg person) within 6–8 weeks.
| Week | Pack weight (80 kg person) | Session duration | Est. calories/session |
|---|---|---|---|
| 1–2 | 8 kg | 30 min | ~280 |
| 3–4 | 10 kg | 40 min | ~390 |
| 5–6 | 12 kg | 45 min | ~460 |
| 7–8 | 14 kg | 50 min | ~530 |

Gear: What You Actually Need
Backpack — The most important piece of equipment. A floppy, cheap daypack will cause shoulder and lower back pain because weight sits low and away from your back. Look for:
- Internal frame or padded back panel
- Hip belt (transfers weight from shoulders to hips)
- Sternum strap
- Loads at or above the hips, close to your spine
A military-style rucksack (MOLLE, ALICE frame) or a dedicated ruck pack (GoRuck, 5.11, Osprey) works well. Any well-fitted hiking pack with a hip belt works fine for beginners.
Weight — You don’t need ruck plates. Options:
- Books or a water jug (2L water = 2 kg)
- Sandbag liner inside the pack
- Standard weight plates wrapped in a towel
- Dedicated ruck plates (flat, sit against your back — better weight distribution)
Footwear — Trail running shoes or hiking boots. Avoid thin-soled road running shoes for heavy packs — you need lateral stability. Boots are optional for beginners but help on uneven terrain.
No special clothing required. Moisture-wicking shirt, comfortable trousers or shorts, and your normal walking shoes are sufficient for your first several weeks.
Rucking Form: 5 Key Points
Poor posture causes most rucking injuries. Focus on these during every session:
- Shoulders back and down — Do not round your shoulders or hunch forward. Think: chest proud, shoulder blades pulled together.
- Weight high and close — Pack should sit high on your back, close to your spine. Weight that hangs away from your body creates a lever that stresses your lower back.
- Engage your core — Light core tension throughout. This stabilises your spine under load.
- Look up — Don’t stare at the ground. Head neutral, chin level.
- Normal stride — Don’t shorten your stride to compensate for the weight. Walk normally.
Your First 4-Week Plan
Week 1: Introduction
- 3 sessions of 20–30 minutes
- Flat terrain, comfortable pace (4–4.5 km/h)
- 5–8% of bodyweight
- Focus entirely on form
Week 2: Build Duration
- 3 sessions of 30–35 minutes
- Same weight as week 1
- Add slight hills if available
Week 3: Add Weight
- 3 sessions of 35–40 minutes
- Increase pack weight by 2–2.5 kg
- Maintain the same pace — don’t speed up yet
Week 4: Add Frequency
- 4 sessions — add one shorter (20 min) session
- Same weight as week 3
- If no soreness or discomfort, you’re ready to progress
After Week 4, use the rucking for weight loss plan to plan your next 8 weeks with calorie deficit targets.
Warning Signs to Take Seriously
Stop the session and rest (or see a physio) if you experience:
- Sharp lower back pain — usually means weight is too heavy or sitting too low
- Knee pain — often downhill with heavy loads; reduce weight or grade
- Shoulder pain at the neck — pack shoulder straps too tight; use the hip belt to transfer weight
- Numbness or tingling in arms — straps compressing nerves; loosen and refit
Dull muscle soreness in glutes, hamstrings, and shoulders is normal in the first 2 weeks. Sharp or joint pain is not.
What to Expect: Calorie Burn Benchmarks
For reference: a beginner at 80 kg rucking with 8 kg at 4.5 km/h burns roughly 6.5–7 calories per minute using the Pandolf equation. A 30-minute session burns approximately 195–210 calories — about the same as a 20-minute jog, with far less impact on joints.
By Week 8 with 14 kg at 5 km/h, that same person burns roughly 9.5–10 calories per minute — comparable to sustained cycling or light running.
