Very effective workout equipment. I use these for upper body workouts (back, arms, chest) and they have been lasting me for about 2 months now. I was afraid they might be cheap because you never know with Amazon, but everything came in good condition. I’ve been using them in every single workout and they have enhanced my upper body progress. This is perfect for those who don’t want to spend the money on expensive equipment. It can be used for home workouts, so it’s quarantine friendly!
