We have you covered here.  As a special bonus to our new members, we will give you TWO FREE 1-hour personal training sessions.  A solid, thoughtful and safe start to your time here at CrossFit Merrimack is very important to us.

In these two sessions you will learn with your coach in a private one-on-one setting the fundamentals of movement, gymnastics, weightlifting, and other common CrossFit movements.  These will be hands-on sessions, so be prepared to move around–but we have all the equipment you will need.

It will be a customized program to fit your individual needs whatever they may be. Personal training can be done on an hourly or 30 minute basis depending on what suits you best.
