《節奏拳擊2 用Wii享瘦》（Shape Boxing: Wii de Enjoy Diet!2/シェイプボクシング2 Wiiでエンジョイダイエット!）是Rocket Company製作並在2010年11月11日於日本發售的體感健身遊戲，是2008年推出的《節奏拳擊 用Wii享瘦（Shape Boxing: Wii de Enjoy Diet!）》的續作。結合音樂與運動的休閒娛樂作品，在當時日本家庭健身市場中最受歡迎的Wii健身遊戲系列之一，並在後來成為Switch《Fitness Boxing》的精神前身。

主打理念並非競技格鬥，而是藉由「拳擊姿勢」與節奏感訓練來達成全身燃脂與雕塑體態的目的，並結合Wii體感控制器，將運動與遊戲結合得更緊密。不再是單純地操作角色，而是在客廳中親自揮拳、閃躲、出勾拳，透過身體律動來完成拳擊節奏訓練。

雖然主要是健身導向，但加入簡單的角色互動與訓練劇情，讓整體訓練過程更具沉浸感。雖然沒有明確劇情線，但隱約透過教練的語氣與進度提示營造出「你正在接受專業指導並逐步成長」的氛圍，帶出與虛擬教練共同奮鬥的健身旅程感。

最大特色是透過Wii Remote與Nunchuk的體感偵測來捕捉揮拳動作，並在節奏樂曲中進行各種拳擊招式訓練，如直拳（Jab）、勾拳（Hook）、上鉤拳（Uppercut），還有左右閃避（Dodge）與防禦（Guard）等。畫面會顯示對應指令與節奏時間軸，需配合音樂準確揮拳，才能獲得高分與燃燒卡路里。系統提供多種訓練模式，包括：

日常訓練：由教練設計的每日運動菜單，可依個人需求調整強度與時長。

自由模式：可自選音樂與拳擊組合進行自由訓練，適合放鬆或針對特定動作加強。

測量與記錄：每日運動後可輸入體重與BMI，系統自動生成圖表追蹤健身進度。

雙人對戰模式：讓兩位玩家同時參與比拼節奏準確度，增添娛樂與互動性。

音樂方面，精選多首經典與流行旋律的類似曲（非原唱版），風格涵蓋J-Pop、Dance、Rock等，並以鼓點強烈、節奏清晰為主，適合進行拳擊動作的拍點練習。例如會出現像是「Survivor風」、「ABBA風」、「Judy and Mary風」的節奏歌曲，每首曲子長度在2~3分鐘之間，設計上既兼顧運動強度又不至於疲勞過度。

完成每首歌曲後會獲得成績評價（如Excellent、Great、Above Average等），系統還會估算卡路里消耗，並可設定目標，例如「一週減少500g」、「30分鐘訓練3次」等，幫助培養運動習慣。

在發售當時廣受日本家庭主婦、年輕女性與健身入門族群喜愛。相較於前作，改進動作感應的準確度、增加教練角色、音樂選項與記錄系統，提供更完整的健身菜單，因此在Wii健身類作品中有著非常穩定的銷量與口碑。許多玩家評價本作操作簡單、節奏感佳，即便不擅長玩傳統遊戲也能輕鬆上手，加上教練語音與角色插圖設計親切有趣，讓人產生持續訓練的動力。不少使用者在網路留言表示靠這款遊戲在家成功減重數公斤，或將其作為每日晨間運動的一部分。

在遊戲專業媒體方面，雖然並未獲得如《Wii Fit》般的國際關注，但多數評論都將它視為「小眾但誠意十足的健身佳作」。其準確度雖然仍受限於Wii的紅外線體感技術，但整體執行流暢，沒有明顯Bug或瑕疵，足以支撐長時間遊玩。更重要的是，成為後來Switch平台《Fitness Boxing》系列的原型與基礎。當Rocket Company將開發團隊重新組織為Imagineer後，他們沿用「節奏拳擊」這核心概念，創作出更加現代化的版本，並延伸出全球熱賣的健身系列。因此，也可說是任天堂健身遊戲歷史中的關鍵轉捩點。

總結來說，《節奏拳擊2 用Wii享瘦》將健身與節奏遊戲巧妙結合、帶有持續訓練系統的佳作。並不以娛樂性為唯一訴求，而是更專注於實用與可持續性，為Wii時代玩家提供在客廳中健康燃脂的道路。或許不是最華麗、最刺激的Wii遊戲，卻是最能持久陪伴玩家的那種。

Shape Boxing: Wii de Enjoy Diet! 2 (シェイプボクシング2 Wiiでエンジョイダイエット!) is a motion-based fitness game developed by Rocket Company and released in Japan on November 11, 2010. It serves as the sequel to 2008’s Shape Boxing: Wii de Enjoy Diet!, combining music and exercise into a casual entertainment experience. At the time, it was one of the most popular fitness game series for the Wii in Japan and later became the spiritual predecessor to the Fitness Boxing series on the Nintendo Switch.

The main concept is not about competitive fighting, but rather about using "boxing movements" and rhythm training to achieve full-body fat burning and body sculpting goals. By utilizing the Wii’s motion-sensing controllers, the game tightly integrates exercise with gameplay. Instead of merely controlling a character on screen, players physically throw punches, dodge, and perform hooks in their living rooms, completing rhythmic boxing routines through real body movement.

While the focus is fitness, the game also incorporates light character interaction and training-themed storytelling to enhance immersion. Although there is no explicit storyline, the coaches' dialogue and progress prompts subtly create the feeling that players are undergoing professional training and gradually improving, fostering a sense of embarking on a fitness journey alongside a virtual trainer.

The core feature lies in detecting punching motions using the Wii Remote and Nunchuk, with gameplay involving various boxing techniques like Jab, Hook, Uppercut, as well as Dodging and Guarding. On-screen prompts and rhythm timelines guide players to punch accurately to the beat of the music, rewarding precision with high scores and promoting calorie burn.

Several training modes are available:

• Daily Training: A daily workout menu designed by the coaches, adjustable in intensity and duration based on personal needs.
• Free Mode: Allows players to select music and boxing combinations for free training, ideal for relaxed sessions or targeted practice.
• Measurement and Record Tracking: After each session, players can input their weight and BMI, with the system automatically generating graphs to track fitness progress.
• Two-Player Versus Mode: Two players can participate simultaneously, competing for rhythm accuracy to add fun and interaction.

The music selection includes a variety of classic and pop-inspired songs (cover versions, not original artist recordings), spanning genres such as J-Pop, Dance, and Rock. Tracks are chosen for strong drumbeats and clear rhythms, making them ideal for boxing workouts. Players will encounter songs styled like "Survivor," "ABBA," or "Judy and Mary," each lasting about 2–3 minutes—long enough to ensure effective exercise without causing overexertion.

Upon completing a track, players receive performance ratings (e.g., Excellent, Great, Above Average), and the system estimates calories burned. It also allows users to set personal fitness goals, such as "lose 500g in a week" or "train for 30 minutes three times a week," helping to build sustainable exercise habits.

At the time of release, the game was highly popular among Japanese housewives, young women, and fitness beginners. Compared to its predecessor, it improved motion detection accuracy, added new coach characters, expanded music choices, and enhanced tracking features, offering a more complete fitness package. As a result, it achieved steady sales and maintained a strong reputation within the Wii fitness genre.

Many players praised the game’s simple controls and good sense of rhythm, making it accessible even to those unfamiliar with traditional gaming. The friendly voice guidance and charming character illustrations provided extra motivation to keep training. Numerous users reported online that they successfully lost several kilograms using the game at home or incorporated it into their daily morning workout routine.

In professional reviews, while it did not gain international attention like Wii Fit, it was widely regarded as "a niche yet sincere fitness gem." Although its accuracy was still limited by the Wii’s infrared motion technology, the game executed its concepts smoothly without major bugs or flaws, making it reliable for long-term play.

More importantly, it laid the foundation for the Fitness Boxing series on the Nintendo Switch. After Rocket Company restructured into Imagineer, they retained the "rhythm boxing" concept and developed a modernized version, which eventually grew into a globally popular fitness franchise. Therefore, Shape Boxing 2 can be seen as a key turning point in the history of Nintendo’s fitness games.

In conclusion, Shape Boxing: Wii de Enjoy Diet! 2 is a well-crafted combination of fitness and rhythm gameplay, offering a sustainable training system. It does not seek to provide flashy entertainment alone but focuses on practicality and long-term engagement, offering Wii-era players a pathway to healthy living from their own living rooms. It may not be the most glamorous or exhilarating Wii title, but it is the kind that stays with players for the long haul.
