Fitness coach: daily walks may not boost fitness

Sumit Dubey, fitness coach and founder of Sumit Dubey Fitness (SDF), says intensity matters: a comfortable pace does not improve cardiovascular fitness as much as a faster pace where you can talk but not sing.

Following identical paths, pace, and timing daily leads to slowed progress; varying pace, length, or incline, or mixing fast and slow walking, benefits the heart.

Walking alone is insufficient without strength training; lifting two or three times a week improves caloric expenditure, strategic function, and body control.

Posture affects walking effectiveness: lifting your gaze, tightening your stomach, and letting arms move freely can enhance the workout.
