You will love this walking exercise if you have more than 5kgs to lose. You only need 2kg dumbbells and a little determination.
Focus on maintaining intensity throughout the workout so you burn the most calories possible. And you have time, do it twice to make it a 40-minute session.
Doing short workouts like this one daily is more effective than doing 3 long workouts a week. Consistency definitely beats occasional intensity.
Enjoy the walking exercise for weight loss with dumbbells.
