Looking for lightweight, inexpensive fitness equipment? Then tubing is for you! It’s great for progressive resistance training, in which you challenge the muscles by increasing the resistance level, number of repetitions, and number of sets.
Generally, light-color tubing provides light resistance and darker colors provide more. Shannon Fable, American Council on Exercise group fitness instructor of the year, recommends tubing with handles that are easy to hold. Tubing is sold in most sporting goods stores and online starting at $10.
