Arm workouts with resistance bands might not look that challenging, but if you've ever tried to pull or push the taught elastic you'll know that they do, in fact, deliver a huge burn.
Arm workouts target your biceps and triceps, the muscles that run down the front and back of your upper arms respectively. And while arm day might feel like the most skippable of days, you'd be silly to make that mistake. Research from The University of Glasgow found that upper-body muscle weakness is associated with a higher hazard for all health outcomes, including cardiovascular disease and cancer. Weak grip strength was even shown to be a bigger predictor for mortality than low physical activity.
