I highly recommend Sam Cosh. He's an excellent and enthusiastic personal trainer. He knows lots of little tricks and tweaks to enhance muscle growth and improve flexibility. Just a finished a week of three great sessions.
I've been training with Samuel now for 5 months and have enjoyed every session. To say he's new to the game he's got a great passion for his work, extremely professional, ready and waiting every day and above all else he's a good laugh too.
