Su Ronghan really didn't know what was on the fourth floor, she knew that there was a staircase going up, and at the end was a small space with two doors on the wall. She thought that both doors led to the rooftop, which is about the same design in a typical house, and then the rooftop would be covered with clothes and quilts, as was the case in the old apartment she used to live in.

The small space on the fourth floor of the Su family is different from the dusty and sandy staircase on the top floor of the old apartment, which looks clean and clean, with only a small window leading to the outside, and an orange lamp on the top. Su Mingzheng used the key to open the door on the left-hand side and pressed the light inside.

In front of Su Ronghan is a wide and high-ceilinged space, which makes people feel comfortable at first glance, in addition to being spacious, there is also a whole wall of floor-to-ceiling windows, if it is not at night, you should be able to see the distant scenery.

But what was placed in the room was not ordinary furniture, but several huge black machines, at least that's what Su Ronghan judged at first glance.

"Come here. Su Mingzheng tied her hair into a short ponytail, and Su Ronghan realized that she was not wearing her usual home clothes or pajamas, but wearing a breathable short-sleeved shirt and shorts suitable for sports, and then guessed her intentions.

Su Mingzheng led his sister to the huge equipment and introduced, "This is a treadmill." ”

"It's an exercise bike. "If you look closely, it's similar to a bicycle, but the wheels don't touch the ground.

"That's a four-seater multi-function weight training machine, have you heard of it: heavy training?" Su Mingzheng pointed to the most huge and complex machine, like an iron shelf.

Su Ronghan shook her head. I'm sorry, she's a dirt bun, she really hasn't been to the gym, and she doesn't know that this spacious room is a private gym.

"You've always heard of weightlifting, right?" Su Mingzheng looked down at his sister who was a head shorter.

This time Su Ronghan nodded, the Olympics have this project.

"It's about using weights to train the muscles in your body. ”

Su Ronghan's eyes widened, that's not... It's scary? The muscles of the Olympic weightlifters are terrifying.

"Are you afraid when you hear that you will train muscles?" Su Mingzheng seems to know this mentality very well, "There are two kinds of exercise: aerobic exercise and anaerobic exercise, running and pedaling exercise bikes are aerobic exercises, which can reduce fat and train lung capacity, but anaerobic exercises such as weightlifting are also indispensable, which can strengthen the muscles in the body and enhance muscle endurance and strength." Such a detailed explanation is very lecturer-like, which makes Su Ronghan feel that she is both patient and gentle.

"It seems too serious? In short, don't think that having muscles is bad, more muscles will increase fat burning, you can also dress with good lines, I heard that training chest muscles can also make your breasts bigger. In the end, Su Mingzheng laughed and suppressed it, Su Ronghan couldn't help but put her arms across her chest, wondering if she was laughing at herself?

"Ahem, it's best to do aerobic exercise first, and then do anaerobic while your body is still hot. This weight training machine can train many parts of the muscles, ask me when you want to use it, I will teach you slowly, and the standard movement will not be injured. ”

When it comes to this issue, Su Mingzheng is still very serious, sports injuries must be avoided.

"This is my private base," Su Mingzheng showed a hint of pride, this place was built according to her requirements, although it was simple, but it was equivalent to moving the core of a professional gym to her home.

"Tomorrow I will copy a copy of the key for you, you exercise for at least half an hour before taking a shower every night, don't think that it is a waste of time, exercise can relieve stress, lest you accumulate into a neurotic disorder before the exam, I did this when I was in my junior year of high school. "Sister has experience, you study hard, Su Mingzheng said so.

"I won't get fat this way!" finally added with the original intention.

Su Ronghan was still a little stunned, and suddenly saw this kind of posture, which she could not accept quickly.

She finally remembered a place like the gym, which she hadn't seen on TV before—it was amazing, she could set up a gym at home, it was... Rich......

However, listening to Su Mingzheng's explanation, she also became a little eager to try, but the advanced concept of girls exercising muscles still makes people hesitate.

She involuntarily poked Su Mingzheng's arm, which was quite tight, "So sister, do you have muscles?" suddenly remembered the appearance of a female version of Mr. Bodybuilding.

Su Mingzheng knew that Su Ronghan was a scholar, and if she gave her time to check the number of jù, she would know that what she said was right, but Su Mingzheng wanted to tease her, so she nodded.

"I've got some practice—do you want to give it a try?" the beautiful sister said with a serious expression.

How do you want to try it? Su Ronghan nodded before she thought of it.

So when Su Ronghan was still confused, Su Mingzheng quietly approached behind her, and suddenly said, "Hold my shoulder." Suddenly, Su Ronghan felt that her feet were off the ground, and in a hurry, she had to intuitively and obediently hug Su Mingzheng's shoulder.

After taking two deep breaths, Su Ronghan finally found that she was being picked up, and her panicked appearance made Su Mingzheng feel like a scared rabbit.

This is a traditional princess hug, Su Mingzheng who is holding the person stands up straight, to put it mildly, but the girl who is being hugged nervously grabs her shoulders and hides her head in her arms, until she finds that she does not need to be afraid before raising her head, it is the little white rabbit who only began to look.

Su Mingzheng, who was playing badly, simply began to circle around the room, showing how easy his steps were.

"I believe my sister has practiced, right?"

Su Mingzheng is only wearing a light and well-fitting sportswear at the moment, and getting close is no different from sticking directly to her body, she can directly absorb the heat from her body, hearing the heartbeat in her chest, Su Ronghan felt very twisted, and said in a snort: "I'm very heavy......"

"It's not heavy!" When the girl was feeling happy, "I can even hold Equation Han!" Su Ronghan secretly leaned her head back on the shoulder that was very close, even if she knew that hugging that Equation Han was probably just a joke between friends, the mood was still... Not happy.

Su Ronghan shook her head, how could she become so willful? She cheered up again.

"Let me go. She demanded.

Su Ronghan, who stood back on the ground, blinked, and re-observed her sister's figure, so slender but very straight, if you look closely, she is not skinny, and the limbs that can be seen are attached to healthy and strong muscles, no wonder, compared to others, it is special and good-looking.

Such a figure is a bit similar to the group of girls who are good at sports in school, but Su Ronghan never thought that Su Mingzheng likes sports, because she is like a big lady who likes indoors...... That's what Su Ronghan thought, and now she finds out that it's right, she is a big lady who likes indoors, just exercise indoors - she won't tan yet.

"I'll try the treadmill first!" Su Ronghan raised her head and made up her mind to follow in her sister's footsteps, starting with the most familiar running.

In fact, she is not a girl who is good at sports, especially ball games that require skills, how many of the top students are good at sports?

"Change your sneakers first. Facing his energetic sister, Su Mingzheng decided to maintain the image of a strict teacher.

Then led the warm-up action, Su Mingzheng sat on the fitness bike, looked at Su Ronghan on the treadmill, changed into sneakers, and changed into clothes suitable for sports, but ...... I glanced at a place that was shaking violently, and then secretly looked away, which was really a little embarrassing.

It's time to take her to buy something, Su Mingzheng planned in his mind.

The next night, when Su Ronghan saw the key hanging on the doorknob with a rope at the door of her room, a happy smile slowly spread on her face.

Even if this must be Su Mingzheng asked others to copy, it is impossible for the eldest lady to do this kind of chores herself, but Su Ronghan held the rope and saw the iron-gray key dangling in front of her eyes, but she couldn't take her eyes off it, and the smile on her face bloomed like a flower, until she was afraid that Su Mingzheng, who would go upstairs later, would see it, so she sneaked behind the door and continued to have fun in the room.

It's my sister's secret base—but she's willing to share it for herself. The meaning is naturally different, and Su Ronghan feels that she has been initially accepted.
