I must tell you that I am very poor in counting while doing exercise. But now I got Talking Dumbbells which will track number of repetitions. The Everlast Talking Dumbbells act as your personal trainer and count your reps out while you work out, so that you will be able to stay focused for a more effective workout.
The Talking Dumbbells have an in-built computer to keep track of your number of repetitions, lifts per minute, amount of calories burned during your session, and the total session time. The other features of the Talking Dumbbells are following:
1) Fill weights with up to 4 pounds of water to adjust workout difficulty
2) Built-in computer monitors number of reps, lifts per minute, calories burned and total workout time
