WONDER Core ワンダーコア 腹筋マシン 筋トレ エクササイズ

自宅で手軽に本格的なトレーニングができる腹筋マシン「WONDER Core(ワンダーコア)」を出品いたします。

体を倒すだけで腹筋を刺激し、運動をサポートしてくれる仕組みが特徴です。ジムに通う時間がなかなか取れない方や、薄着になる季節に向けて無理なくシェイプアップを始めたい方に適しています。

本体は、背もたれ部分のクッション性の高いローラーが背中や腰を心地よく支え、倒れる時だけでなく起き上がる時もしっかりと補助してくれる設計です。スプリングの強さを調整することで、ご自身の体力や目標に合わせた負荷でトレーニングを行うことができます。腹筋運動だけでなく、ひねりを加えたクランク運動や、下半身を意識したエクササイズなど、これ一台で複数のメニューに対応が可能です。
使用しない時は、中央のロックを解除してコンパクトに折り畳むことができるため、ベッドの下や家具の隙間など、お部屋の限られたスペースにすっきりと収納できます。

【商品の状態】
日常的なエクササイズに使用していたため、フレーム部分に細かな擦れ傷や、ウレタンローラーに多少のへこみなどの使用感は見受けられますが、シートの大きな破れや目立つ汚れはなく、全体的に清潔感を保っています。スプリングの伸縮や可動部の動きもスムーズで、本来のトレーニング機能を十分に発揮できる状態です。

【仕様】
カラー:グリーン × ホワイト
機能:折り畳み収納可能、負荷調整機能付き

【ご購入にあたって】
商品は自宅の室内にて保管しており、出品にあたりアルコールを用いて丁寧に清拭いたしました。
発送の際は、配送時の破損を防ぐために一部のパーツを分解し、緩衝材で保護した上で、再利用の段ボール箱を用いた簡易包装にてお届けいたします。組み立てに必要な工具や手順はシンプルな造りとなっております。

中古のフィットネス機器であることをご理解の上、毎日の健康的な習慣作りにぜひお役立てください。
