How to prepare your body for a first big trek with rucking: starting weight, safe weekly progression, and beginner mistakes to avoid.
"Is regular endurance training enough to prepare for my first big trek?" Honest answer: not quite — you're missing the adaptation to weight on your back over hours, and the best way to train that is exactly that way: walking loaded, known as rucking. Beginners start with roughly 10 percent of their body weight — at 75 kilos, that's about 7.5 kilos, roughly a large case of water bottles strapped to your back.
Progress can't be rushed: total load (distance times weight) should increase by no more than roughly 10 percent per week — and distance and weight are never increased in the same week. One lever at a time, not both at once.
This starting load is enough to accustom your back, hips, and shoulders to the new demand without breaking down posture and gait. Starting straight at your full trekking weight overloads tendons and joints before your muscles can catch up.
Build up distance for two to three weeks first, then increase weight in small steps. This separation prevents overtiredness building up on two fronts simultaneously.
Include a training week with two rucking sessions on consecutive days, as close as possible to the real trip rhythm — that way you test cumulative load, not just single-session load.
For advanced trekkers, a realistic target sits around a quarter of body weight; noticeably more than around a third of your own weight counts as an unnecessarily high risk for back and joints, even with good fitness.
A loaded backpack shifts your center of gravity backward and demands more from your core and ankles than unloaded walking. Add short core-stability and balance exercises one to two times a week (e.g. single-leg stands, planks) — they complement pure rucking and further reduce the risk of a twisted ankle on uneven trekking terrain.
Loaded backpack training stresses your back, knees, and shoulders differently than pure running or endurance training — pain that outlasts the training day is a stop signal, not "breaking in." If you have pre-existing knee, hip, or back issues, start lower and progress slower than described here. Never start rucking training in brand-new shoes — that combines two risk factors at once. Also make sure you get enough sleep between rucking sessions — tendons and ligaments adapt to the new pulling load mainly during recovery, not during the training session itself.
Train in exactly the shoes, socks, and backpack you'll use on the actual trip. Rucking isn't just strength and endurance training — it's also the best blister test there is, since pressure points show up completely differently under load than on a light stroll.
Roughly 10 percent of your body weight is a sensible start — at 70 kilos, about 7 kilos. From there, increase slowly, never weight and distance in the same week.
One to two sessions per week is enough for most beginners. More frequent training raises the risk of overloading shoulders, back, and knees without adding extra benefit.
As a rough ceiling: don't train permanently above a third of your body weight. Advanced trekkers typically stay around a quarter of body weight, not above it.
Several weeks ahead, with slow, weekly increases. Starting just two weeks out leaves no time to gradually adapt to load and distance — which raises injury risk on the trip itself.
Not strictly necessary, but useful as a complement: rucking mainly trains trekking-specific endurance under load, while classic strength and core training builds the base strength that keeps your steps stable even when fatigued.
