Begin in a forward lunge position with one foot flat on the ground and the other leg extended behind you, with the back knee resting gently on the floor.
Hold a weight (e.g., a dumbbell or kettlebell) and place it on your front thigh, just above the knee.
Keeping your front heel flat on the ground, bend your front knee and shift your body weight forward to deepen the stretch.
Make sure your back is straight, and your hips are square as you lean into the stretch.
Hold this position, feeling the stretch deep in your lower calf (soleus) while keeping the weight stable on your thigh.
Hold/maintain as prescribed by your physiotherapist.
