For the next month, Sakura went though hell. 

The Queen had decided to work on endurance first, and made her run laps around the village every day.

However, as harsh as the training was, Sakura was definitely seeing an improvement. At first, she could barely run one lap. But now, she could run over ten laps without even breaking a sweat.

On top of that, the Queen had worked on Sakura's muscles and speed, by giving her chakra bands to put on her ankles and arms. By putting chakra into them, you could make them quite heavy. The more chakra in them, the heavier they got. The Queen added a little more chakra into each band by the end of each day. Sakura wasn't allowed to take them off at all. She had to sleep, shower, and eat with them on. Her parents had, of course, noticed these bracelets of their daughters wrists, but dismissed them as the latest fashion.

Sakura and the Queen had also become closer and closer during the training sessions (which were everyday, and all day).

Sakura, instead of dreading training, loved it. She especially loved the way she felt after a particularly tough work out. Once the tiredness had faded, Sakura always felt so refreshed.

But of course, no one knew about this. It was Sakura's little secret.
