For someone starting out as a Personal Trainer and growing my membership online and locally. I was looking for a website along with a cloud based online solution. I needed something quick and didn’t cost a lot. I have stumbled across onlinegymsoftware.com that is powered by a company named fitsoft. They website they give out is pretty decent.
You can find them here http://onlinegymsoftware.com. They have a membership management system and a staff area for login. You need to email them what you need. They don’t turn on all the features for starters. They have updated their system pretty often with new features.
I got a free online gym software and a website within a couple of days. You can check out their pricing on the website to see if it fits with your business. I find that when I am away on vacation and not offering any classes for that timeframe I do not have to pay for anything which is sweet 🙂 Last time I have contacted them they also have an enterprise solution.
I hope that helps you find the right solution.
