There is no substitute for consistency. You must consistently exercise your muscles, your heart, your lungs, and your mind. You must consistently stretch your body, your heart, and your mind. Consistency is not 2 days a week or every now and then. It is every day! Every day get up and move, get uncomfortable. Every day reward that movement with stretching. If you are consistent your body will thank you. If you are consistent your heart and mind will thank you. If you are consistent your body will reward you with the things that you will be able to do.
If you are consistent you will enjoy a life worth living!
