________________ are single dumbbells that are held independently in each hand.
Single dumbbells are individual weights that are held independently in each hand during a workout or exercise routine. They are designed to provide resistance and help improve strength, balance, and coordination. Single dumbbells are typically made with a metal or rubber-coated handle and removable weight plates, allowing the user to adjust the weight according to their fitness level and goals. They are commonly used for various exercises, such as bicep curls, shoulder presses, lunges, and chest presses. Single dumbbells offer versatility and can be used by individuals of different fitness levels, making them a popular choice for strength training and overall fitness.

There is no difference
Universal machines and free weights are different in several ways.
- Universal machines typically have a fixed range of motion, meaning they guide your movement along a specific path. Free weights, on the other hand, allow for greater freedom of movement, as you are responsible for controlling the weights in all directions.
- Universal machines often have adjustable weight stacks, making it easy to change the resistance. With free weights, you have to manually add or remove weight plates to adjust the load.
- Universal machines usually have an ergonomic design, including padded seats and handles, to provide stability and comfort during exercise. Free weights require you to stabilize yourself, which can engage more muscles for balance and coordination.
- Universal machines often have built-in safety features, such as weight stacks enclosed within a machine frame, preventing the weights from falling or causing injury. Free weights require proper form and technique to avoid accidents, as there is a risk of dropping the weights without proper control.
- Universal machines can be beneficial for beginners or those recovering from injuries since they offer more stability and can isolate specific muscle groups. Free weights, on the other hand, allow for more functional and compound movements, engaging multiple muscles at once and mimicking real-life activities.
- Universal machines are commonly found in commercial gyms or fitness centers, while free weights can be used at home or in a variety of settings.
Overall, the main difference between universal machines and free weights lies in their range of motion, resistance adjustment, stability, safety features, and versatility of exercises.
