The other day, I participated in a trial session held at a local event and had a really fun time. I think this workout is perfect for women in their 30s and 40s, as it really works on your butt in a short amount of time! Also, the female instructor had a very nice smile, and the participants (mothers and children alike) seemed to be having a lot of fun. Training to the music that was playing really lifted my mood and made it feel like a party. This is worth experiencing once! !

昨年9月からグループレッスンに通っています。 めちゃくちゃ運動音痴で運動嫌いの私でも継続して通えています…！ まずトレーナーのおしり工場員が明るくて元気が貰えます！これだけでも行く価値がある。 グループレッスンとはいっても5〜8人程度の少人数なのでフォームを見てもらえて直して貰えます。 トレーニングは優しすぎないけどキツすぎないちょうどいい感じ、コツが掴めれば筋肉痛もやってきます😭 キツい時も皆で恥じらいなく叫んで、一体感の中でキツいレッスンも乗り越えられます！ おしりの形が歳を重ねるごとに好きじゃ無くなってましたが、最近は丸みを帯びてきて自分のおしりが好きになってきました。 運動って楽しいものなんだ！と30過ぎてからやっと気づくことができました。ありがとう！ これからもよろしくお願いします！

It was my first time using the machine, but the instructions were detailed and easy to understand! Also, the story about food at the beginning was interesting! ! I think I was taught knowledge that I can use for the rest of my life 💕 thank you! Thank you for your continued support.

Let's butt in the dark is tough because you use parts that you don't normally use! There were times when I thought so, but the moody atmosphere in the dark, the music, and the cheerful and encouraging atmosphere from the instructors made it so much fun! It's fun to do it together! I had a lot of muscle pain from the next day, but I realized that it was really effective! I will go again!

初めて伺いましたが、インストラクターの方が周りの方に紹介して下さり、緊張も解けました！ レッスンは思っていたよりかなりキツかったのですが、みなさん楽しんでいる雰囲気で自分のペースで無理なくついていけました。 簡単な動きに見えて、当日から筋肉痛だったので、筋肉や体幹が鍛えられそうです。 インストラクターの方が丁寧に指導してくださり、運動が苦手な私でも頑張れそうです！ おしりを上げて、気分も上げたいと思ったので、また伺います^^

街のイベントなどでも、元気過ぎる無料のグループレッスンをしているOSIRIS factoryさんの パーソナルトレーニングを初体験。 工場長に直接指導してもらいました！ トレーニング前に栄養についての座学もあり どうすればより効率良く自分の理想に近づくかを教えてもらってからのトレーニング。 しっかり筋肉に効いて翌日大変でした。笑 グループレッスンは、テンション爆上げでいつも以上に身体が勝手に動いちゃう感じで楽しい。 女性が多いが、男の自分でもきつい🤣 なまってる男子にはこちらがオススメ！ パーソナルは、効かせたい筋肉に直接負荷かけてるって感じでめっちゃきつい。 体型とか運動音痴とかで人目が気になる人はパーソナルがおすすめ。 自分の合ってる方を選んで通えるジム！ 隠れ家的な場所なので、男心をくすぐるジムです。

5カ月程グループレッスンに通っています。結果お尻の形が綺麗になってきました。 レッスンは暗闇の中なので、恥ずかしさも忘れ叫んで自分を解放することができます。 トレーナーの方の教え方が分かり易く回って来て正しいフォームに直してくれます。元気なトレーナーの声に励まされながら一時間集中すると、いい汗をかいてとても気持ちよいです。 ココロもお尻も上向きに、その通り！ おすすめです。

おしり工場さんに、出会えたおかげで ほんとに人生また違う方面で楽しみをみつけられたし、体も心も上向きにの合言葉どおり、めっちゃたのしくて、ハルカ先生もめっちゃかっこ可愛くてサイコー！！ここに通わないのは損だなと思う毎日です。3.5キロ痩せたのもみんなで楽しく頑張れるからだとおもいました。おすすめです。

I go to group lessons. I couldn't do it well at first, but the instructors were fun and kind and taught me how to work my muscles, so I felt at ease. It's been about 9 months since I started attending, and I'm still getting my form checked and guidance on how to improve my training. The lessons are held in the dark with loud music 🎶 and everyone sings out loud, so even the tough muscle training is fun and ends in no time. And muscle pain the next day... Ah, it's the timing when you can feel that you're training well. I've made new friends and it's always fun🌟

Even though I'm not good at exercise, I was able to enjoy the class thanks to the detailed lectures given by the energetic and wonderful instructors. Training in the dark with a mirror ball while everyone chants “Let’s Butt” is highly entertaining! I felt that it was an experience that could only be had here.

I feel like I'm using muscles in areas that I don't usually pay attention to, and I feel like I'm going to cramp up, and sometimes I'm going to make a noise, but I can feel that it's working, so I keep exercising. I have a feeling that this is true. With instructor Haruka's energetic shouts, let's try a little harder! I feel that way and my motivation increases. Personally, I enjoy lessons in the dark with a mirror ball spinning around, making it even more exciting!

Exercise after thorough explanation Check whether you are performing the exercise correctly In group lessons, even if it's hard, you can have fun and see it through to the end! 😊

I went to try it out with a friend. With a moody atmosphere and motivating music, I had fun moving my body! I consciously used muscles that I don't normally use, so there were moments when I thought it was tough, but thanks to the trainer's encouragement, I was able to finish until the end.

With instructor Haruka's cheerful smile, shouts, and guidance, you'll be able to smile and enjoy even though it's tough from beginning to end ^_^ The different atmosphere of music and lighting further increases the excitement.

When I called him, he came to Tama City, Tokyo. Let's all have a butt! After having fun, the factory manager gave a mini lecture which was very well spoken and interesting!

I had muscle pain in a different area than I expected, which made me more interested in participating next time. Also, the guidance from the person in charge was very accurate, and thanks to them I was laughing right away lol. It was a really great experience and a lot of fun! I will participate again!

In addition to training, we can also provide detailed advice on meals and how to incorporate protein! I always look forward to speaking with the factory manager.
