An easy way to get rid of the 'post-holiday' blues is to start a
Pilates program.
Pilates is easy enough to do before work, at a lunch break or right after work as it is non-evasive and although you will work hard you will not feel exhausted or spent after a 1 hour session. Instead you will feel uplifted, strong and ready to go on with your day. Also, the 'feel good' feeling that you get after a
Pilates session will stay with you for hours and even days. Give it a try - you'll be surprised! :)
