The problem with resistance bands are that they quickly lose tension during the lowering phase of every exercise!
Using standard bars or handles with resistance bands is ineffective!
If you want to see better results, you need to increase the time your muscles are under tension.
Time Under Tension (TUT) refers to the amount of force your muscle exerts in a given time. In essence, it's the length of time your muscle is under strain during a set.
According to Men's Fitness, by "putting a muscle under longer bouts of strain, you can cause extensive muscle breakdown leading to sleeve-busting muscles."
The split bar design of Tension Toner allows you to both pull and lift at the same time, ensuring that your muscles are under tension during the entire movement!
By keeping the bars separated under tension, it encourages you to multitask your muscles for more effective workouts in less time.
