You can build an effective cardio routine in a small apartment with simple movements, a clear plan, and enough room to move safely.

Choose low-space movements

Marching, step touches, controlled knee lifts, and low-impact intervals can raise your heart rate without equipment or jumping.

Use short intervals

Try a few minutes of steady movement followed by an easy recovery period. Start at a comfortable pace and increase gradually over time.

Make the space safer

Clear obstacles, wear stable footwear if needed, and stop if you feel pain or dizziness. Choose exercises that suit your comfort and environment.
