small group personal training
Identify who you’re targeting for your small group: weight loss, women, sport specific, etc. then market to where these people meet up.
Let your current client base know that this is a new offering and offer a referral “reward” for those who sign on. Free sessions work great!
Of course FB, social media is another great way to get the word out.
Identify what makes your small group different and why people would want to attend.
