It depends on what you want to focus on. Think about what your mission and philosophy are (in fitness and in business). Do an online search for “mission statement vs. philosophy” so you understand the difference between the two terms before you develop each. Think about who you want your target market to be (demographic–age range, gender, their goals, etc.) and if that target market exists in your geographic area. These steps should guide you in determining whether you want to offer one type of fitness discipline only (for example Crossfit, martial arts, yoga, dancing, etc.) or a variety of disciplines like big gyms do. Either way, you need to know your target market and offer what they want while also distinguishing yourself from the competition.
