Sand Bag? Rocky Bag?

In a training camp, trainees are told to carry either one, a sand bag(5kg) and a rocky bag(7kg), along the whole training route.

'You'll have to climb up the hill, swim through the river, and walk pass the swampy ground. The whole journey would be around 5 miles,' instructor told the trainees.

By knowing the distance of the journey, most trainees choose the 5 kg sand bag, instead of heavier 7 kg rocky bag.

At the finishing line, those who chosen the rocky bag succeeded, the rest failed. After swim through the river, the 5 kg sand bag become 10 kg, but the rocky bag remain 7 kg.
