Weighted vest - I’ve been walking with one for over a month now and noticed that I’m stronger, I burn more calories and overall my workouts are EASIER because of my improved strength. I’m wearing the 12 lbs vest but start light and work your way to heavier vests. Comes in 8 lbs as well. Also the visor really protects your face from the sun. Looks silly I know but it WORKS 👏🏻 Amazon find Workout Fitness Tennis skirt
