PROBLEM TO BE SOLVED: To provide a lower limb muscle training device capable of easily and appropriately training a calf (mainly a gastrocnemius muscle and a soleus muscle) and a tibialis anterior muscle. SOLUTION: A lower limb muscle training device 10 has a foot resting portion 15 for mounting the sole of a user's foot and a foot resting portion 15 so that the front end portion of the foot resting portion 15 moves up and down. A horizontal shaft 16 that rotatably supports the foot rest portion 15 and a load applying portion that applies a load to the vertical movement of the foot rest portion 15 with respect to the front portion of the foot rest portion 15 are provided. This configuration can train the calf muscles in general, especially the tibialis anterior muscle, which is important for walking movements. In addition, since the load applying part can apply a load to the anterior part of the foot resting part, the responsiveness of the load becomes high, and it is more suitable for the tibialis anterior muscle and the calf (mainly the gastrocnemius muscle and the soleus muscle). Training is possible. [Selection diagram] Fig. 1【課題】ふくらはぎ（主に腓腹筋、ヒラメ筋）、及び前脛骨筋を手軽にかつ適切に鍛えることができる下肢筋肉トレーニング装置を提供する。【解決手段】下肢筋肉トレーニング装置１０は、使用者の足裏を載せるための足載置部１５と、この足載置部１５の前端部が上下に動作するように、足載置部１５を回転可能に支持する水平軸１６と、足載置部１５の前部に対し、足載置部１５の上下動作に負荷をかける負荷付与部と、が備えられている。この構成により、ふくらはぎの筋肉全般、特に歩行時の動作に重要な前脛骨筋を鍛えることができる。また、負荷付与部が足載置部の前部に対して負荷をかけることができるので、負荷の応答性が高くなり、前脛骨筋、及びふくらはぎ（主に腓腹筋、ヒラメ筋）に、より適切なトレーニングが可能となる。【選択図】図１
