There are several types of grips that can be used in indoor cycling:

1. Standard grip: The standard grip is the most common grip used in indoor cycling. It involves placing your hands on the handlebars with your palms facing downward. This grip allows you to control the bike and make small adjustments to your position.
2. Racing grip: The racing grip is similar to the standard grip, but the palms are facing inward towards the body. This grip can be more aerodynamic and is often used by competitive cyclists.
3. Climbing grip: The climbing grip involves placing your hands on the tops of the handlebars and leaning forward. This grip can help to distribute your weight evenly and is often used when cycling uphill.
4. Aero grip: The aero grip involves placing your hands on the aerobars, which are extensions of the handlebars that allow you to tuck your hands in close to your body. This grip is often used by competitive cyclists to improve their aerodynamics.
5. Hammer grip: The hammer grip involves placing your hands on the ends of the handlebars and grasping them like the handle of a hammer. This grip can be used to help distribute your weight evenly and can be helpful when cycling uphill.

It is important to experiment with different grips to find the one that is most comfortable and effective for you. It is also a good idea to maintain proper form and technique to avoid injury and get the most out of your indoor cycling workouts.
