Equipment Needed for STS
STS really doesn't require any more equipment than we have used in our other videos with the one exception being a pull up bar for pull-ups (you can use elastic tubing as an option or substitute another back exercise if you prefer).
The equipment needed for STS is a bench or step, a weight adjustable barbell, a wide variety of dumbbells, a stability ball, a resistance band, paper plates, and good focus. Other pieces of equipment are totally optional such as a pull up bar (or tubing), weighted vest, ankle weights, micro load weighted gloves, and slanted risers.
