Personal Trainers and Coaches

As a club we provide coached training sessions for members and while it's clearly not a practical possibility to give individual attention to all our members a number of club coaches offer their services to individuals privately. There are also a few external coaches that club members have used and we provide contact details here.

Club members seeking individual coaching are invited to contact these people directly. Please note that while we try to keep this information up to date, it is your responsibility to check that whether or not they provide what you seek and any cost involved is between you and them. Most people run their own web site where they can give a more detailed description of what they offer.

Note that neither Serpentine R.C. nor its members may be held responsible for any training or advice given. Before engaging the services of any trainer or coach members should satisfy themselves as to training, experience and insurance.
