I walk in the park every day.

I walk to school every day.

This problem is very difficult.

In order to overcome these difficulties, we all need to cooperate.

I strained a muscle at the gym yesterday.

I started exercises to strengthen the abductor hallucis muscle.

He started a special exercise to strengthen his flexor hallucis longus.

By strengthening the adductor hallucis, you can maintain the health of your feet.

My flexor pollicis brevis hurts.

He is my best friend.
