What Are Kettlebells?

A kettlebell is a cast-iron or adjustable weight with a handle attached above the centre of mass.

Unlike dumbbells, the weight sits below the handle.

This unique design creates different movement patterns and training possibilities.

Popular kettlebell exercises include:

Swings
Goblet squats
Cleans
Snatches
Turkish get-ups
Carries

Because the weight distribution is different, kettlebells often challenge stability and coordination more than traditional dumbbells.

What Are Dumbbells?

Dumbbells are among the oldest and most recognised pieces of strength-training equipment.

The weight is evenly distributed on both sides of the handle.

This makes them highly effective for:

Strength training
Muscle building
Progressive overload
Isolation exercises

Popular dumbbell exercises include:

Bench press
Rows
Shoulder press
Lunges
Bicep curls
Chest flyes

Dumbbells remain a staple in both commercial gyms and home fitness environments.
