《健身拳擊2：節奏運動》（Fit Boxing 2: Rhythm & Exercise）是由日本開發商Imagineer製作，於2020年12月4日在Nintendo Switch平台上推出的健身類遊戲。2019年原作《健身拳擊》的正統續作，承襲原有的節奏拳擊玩法，並針對內容與系統做出多項改良與擴充。遊戲結合節奏遊戲與有氧運動的特點，讓玩家在居家環境中透過簡單的拳擊動作，達到健身與減重效果。

故事性非常輕微，並非以敘事為主，而是圍繞著每日健身的實用功能進行設計。在虛擬教練的指導下，選擇個人目標（例如燃燒脂肪、強化核心、塑身等），並每天進行定制化訓練。這些訓練由預設的課表組成，涵蓋熱身、拳擊主訓練與伸展等內容，強調全身運動。遊戲中包含多達66種節奏組合與拳擊技巧，像是直拳、勾拳、上鉤拳、閃避等動作，玩家需依據音樂節奏與畫面提示進行操作。

操作方面，只需要一對Joy-Con控制器即可完成所有動作，不需要額外器材或健身配備。透過內建的動作偵測功能，遊戲會根據動作準確度給予評價，進而記錄每日表現與消耗的卡路里。除了單人模式外，也支援雙人同樂，與親友一起訓練，提升互動樂趣與運動動力。遊戲內還包含鬧鐘設定功能，能提醒每天固定時間進行健身，鼓勵養成規律運動的習慣。

加入九位虛擬教練，有Lin, Evan, Karen, Hiro, Sophie, Martina, Janice, Laura and Bernardo三位為系列新登場角色，每位教練都具備不同風格、語音與互動方式。透過累積訓練時數與達成目標來解鎖服裝、背景與教練語音變化。除互動性強之外，還有完整的健康追蹤系統，包括消耗卡路里統計、體重變化紀錄、BMI分析與「身體年齡」評估，讓玩家能具體掌握運動成果。

音樂方面，收錄多首改編自流行曲的無詞伴奏版本，例如《Hot N Cold》等，搭配動作指引與節奏視覺特效，為訓練過程增添娛樂感。不過，由於使用的是簡化配樂版本，也有部分玩家反映曲目選擇與節奏感略顯單一。

自推出後，在玩家社群中獲得普遍好評。根據Best Buy用戶評價顯示獲得4.6顆星的高分，超過九成的用戶願意推薦該遊戲。大多數玩家認為這是在疫情或無法外出運動的情況下，極具實用價值的健身工具。儘管部分評論指出偵測系統的準確性仍有待改進，以及音樂內容略為重複，但其簡單、易上手與日常可執行的運動設計仍受到廣泛認可。

綜合來看，《健身拳擊2：節奏運動》將遊戲娛樂性與實際運動效果相結。無論是新手玩家、健身初學者，或是希望維持健康生活習慣的人，都能從本作中獲得實質幫助。不僅延續前作的成功經驗，也透過更豐富的內容與系統優化，打造出更完整的健身遊戲體驗。

Fit Boxing 2: Rhythm & Exercise is a fitness game developed by Japanese studio Imagineer and released on the Nintendo Switch on December 4, 2020. It serves as the direct sequel to the 2019 title Fit Boxing, retaining the original rhythm-based boxing gameplay while introducing numerous improvements and content expansions. The game blends elements of rhythm gaming and aerobic exercise, enabling players to work out and burn calories through simple boxing motions in the comfort of their own homes.

The game places minimal emphasis on narrative and instead focuses on practical, daily fitness functionality. Under the guidance of virtual trainers, players set personal fitness goals—such as fat burning, core strengthening, or body toning—and follow customized training sessions each day. These sessions are composed of preset routines that include warm-ups, main boxing exercises, and cool-down stretches, emphasizing full-body movement. There are up to 66 different rhythm patterns and boxing techniques, including jabs, hooks, uppercuts, and dodges, all performed in time with the music and on-screen prompts.

In terms of controls, all movements are executed using a single pair of Joy-Con controllers, with no additional equipment or accessories required. The game uses built-in motion sensors to evaluate the accuracy of movements, recording performance and calories burned after each session. In addition to solo training, the game also features a two-player mode, allowing users to work out together with friends or family, adding a social and motivational element. A built-in alarm system can also be set to remind players to exercise at regular times, helping to establish a consistent fitness routine.

Nine virtual trainers are available in the game: Lin, Evan, Karen, Hiro, Sophie, Martina, Janice, Laura, and Bernardo. Among them, three are new to the series. Each trainer has a distinct personality, voice, and interaction style. As players accumulate training time and meet fitness goals, they can unlock new outfits, backgrounds, and additional voice lines, further enhancing the game’s interactive appeal. Additionally, a comprehensive health tracking system is included, which provides calorie burn statistics, weight change logs, BMI analysis, and an evaluation of the player’s “fitness age,” giving users a tangible sense of their progress.

Musically, the game features instrumental versions of popular songs, such as “Hot N Cold,” tailored for fitness use. The background visuals and rhythm cues add an engaging layer of entertainment to the training process. However, some players have noted that the music selection feels somewhat repetitive and lacks variety.

Since its release, Fit Boxing 2 has received generally positive feedback from the gaming community. On Best Buy, it holds an impressive 4.6-star rating, with over 90% of users recommending the game. Many players praise it as a valuable fitness tool, especially useful during the pandemic or when outdoor exercise is not feasible. While some criticisms point to occasional inaccuracies in motion detection and repetitive music tracks, the game’s accessibility, straightforward mechanics, and practicality in daily life have earned it broad recognition.

Overall, Fit Boxing 2: Rhythm & Exercise successfully merges the fun of gaming with effective physical activity. Whether you’re a beginner to fitness, a casual player, or someone looking to maintain a healthy lifestyle, this game offers meaningful support. By building on the strengths of its predecessor and enhancing both content and system performance, it delivers a more refined and well-rounded fitness gaming experience.
