《比利的軍事訓練營 用Wii享瘦》（日文原名：ビリーズブートキャンプ Wiiでエンジョイダイエット！，英文名：Billy's Bootcamp: Enjoy Diet on Wii）是由Rocket Company開發與發行，於2008年發行在Wii平台上的健身類遊戲。以美國知名健身教練比利·布蘭克斯（Billy Blanks）所創立的「Billy's Bootcamp」（比利軍事式訓練營）為基礎，將充滿活力的健身訓練課程數位化，搭配Wii體感操作，讓人在家中也能輕鬆跟著比利一起揮汗燃脂。

以一個健身訓練為主題的虛擬訓練營，由比利本人以虛擬形象擔任教練，逐步完成各種運動課程。這些課程涵蓋有氧運動、肌力訓練、柔軟體操及拳擊動作等，目標是透過短時間內高效率燃燒熱量、提升心肺功能與肌肉耐力，同時能夠在家享受專業訓練的氛圍。

操作方面，充分運用Wii Remote與Nunchuk的體感功能，按照螢幕指示做出各種揮拳、踢腿、深蹲、扭腰等動作。會即時偵測動作幅度與節奏，並給予評分與鼓勵，隨時了解自己是否正確執行訓練指令。此外，還提供多種課程模式，例如短時間集中鍛鍊的「快速訓練」、針對特定部位加強的「部分強化訓練」、以及全身綜合鍛鍊的「全面挑戰」。為了增加樂趣，每個訓練動作會搭配節奏感十足的背景音樂，比利也會不斷在旁以熱血口吻打氣，讓整個過程充滿動力與節奏感。

在訓練過程中可以根據自己的進度與體能狀況調整難度，還設有卡路里消耗統計、體能測試以及成就解鎖系統，讓使用者能夠以可視化方式追蹤自己的健身成果。由於是單人向設計，因此每次訓練的節奏與進度都可以依照玩家需求自行安排，非常適合忙碌生活中想要簡單運動的人群。

在視覺表現上，採用明快、陽光的卡通風格。比利的角色模型雖然簡單，但表情動作生動，能有效傳達出那種軍事式訓練特有的激勵感。場景以虛擬健身教室為主，背景簡潔明亮，不會造成視覺干擾，可以專注於自己的動作。音效方面，比利的語音鼓舞與節奏音樂搭配得當，氣氛活潑積極，符合遊戲希望帶動玩家運動熱情的目標。

市場評價方面，在日本推出時，受到喜愛健身與家庭娛樂用戶的一定歡迎。許多玩家認為成功地將「Billy's Bootcamp」的精神搬到Wii平台上，並且操作直覺、體感反應良好，適合初學者或想要在家簡單健身的人使用。尤其是比利本人親自指導、充滿熱情的氛圍，讓不少玩家感到訓練過程中不孤單、充滿幹勁。然而也有批評指出，在動作偵測精度上並不如部分更專業的健身遊戲（如《Wii Fit》系列）來得精準，有時動作偏離正確姿勢，系統仍會判定為成功。此外，課程種類與深度對於進階玩家來說稍嫌單薄，重玩性有限。

總體來說，這是主打輕鬆、動感的健身體感遊戲，特別適合想透過趣味方式燃燒熱量、體驗比利式訓練精神的玩家。對於希望在家健身、又不想太過嚴肅正經的人來說，是輕鬆、熱血又帶點娛樂性的好選擇。

"Billy's Bootcamp: Enjoy Diet on Wii" (Japanese title: ビリーズブートキャンプ Wiiでエンジョイダイエット！) is a fitness game developed and published by Rocket Company, released for the Wii platform in 2008. Based on the famous American fitness instructor Billy Blanks’ original "Billy's Bootcamp" program, the game digitizes his high-energy workout sessions, combining them with the Wii’s motion controls to let players easily sweat and burn calories at home alongside a virtual Billy.

The game presents a virtual training camp centered around fitness training, with Billy Blanks himself appearing as a virtual instructor guiding players through various workout sessions. These sessions include aerobic exercises, strength training, flexibility routines, and boxing-style movements, all aimed at efficiently burning calories in a short time, improving cardiovascular health, and building muscular endurance—all within a professional training atmosphere from the comfort of home.

In terms of controls, the game fully utilizes the motion-sensing capabilities of the Wii Remote and Nunchuk. Players perform a variety of actions such as punching, kicking, squatting, and twisting their waist, following on-screen prompts. The system detects the magnitude and rhythm of movements in real time, providing immediate feedback, scores, and encouragement, helping users monitor whether they are correctly executing the exercises. Multiple course modes are available, including "Quick Training" for short, intense workouts, "Focused Training" targeting specific body parts, and "Full Challenge" for comprehensive whole-body exercises. To keep the workouts fun, each movement is paired with rhythmic background music, and Billy's enthusiastic voice continuously motivates players, creating an energetic and engaging environment.

During training, players can adjust the difficulty based on their physical condition and progress. Features such as calorie burn tracking, fitness tests, and achievement unlock systems allow users to visually monitor their fitness progress. Since the game is designed for single-player use, each workout’s pace and schedule can be customized according to the player’s personal needs, making it very suitable for busy individuals looking for a simple way to exercise at home.

Visually, the game adopts a bright, cheerful cartoon style. While Billy’s character model is simple, his lively expressions and movements successfully convey the motivating spirit typical of military-style training. The setting mainly features a clean and bright virtual fitness studio, ensuring minimal visual distractions so players can focus entirely on their movements. In terms of audio, Billy’s encouraging voice lines are well-matched with the upbeat background music, creating a lively and positive atmosphere that aligns with the game's goal of energizing and motivating players to move.

Regarding market reception, the game was fairly well-received in Japan, especially among fitness enthusiasts and families seeking home entertainment. Many players praised how well it captured the spirit of "Billy's Bootcamp" on the Wii platform, noting its intuitive controls and responsive motion detection, making it ideal for beginners or those simply wanting an easy, home-based fitness experience. Particularly, Billy’s own passionate, encouraging presence helped many players feel less lonely and more motivated during training. However, some criticisms pointed out that the motion detection was not as precise as that of more professional fitness titles (such as the "Wii Fit" series); sometimes, even incorrectly performed movements were judged as successful. Additionally, for more advanced players, the range and depth of the training programs might feel somewhat limited, reducing the game's long-term replay value.

Overall, Billy's Bootcamp: Enjoy Diet on Wii is a light, energetic fitness game designed to help players burn calories and experience the motivating spirit of Billy's training methods in a fun way. It's an ideal choice for those who want to exercise at home without the pressure of overly serious workouts, offering an entertaining, lively alternative to more rigorous fitness programs.
