Using these handgrips is easy. Simply hold one grip in each hand and squeeze the handles together. Do this repeatedly for a set number of times to build hand, arm, and forearm strength. As a stress reliever, you can use them whenever you feel stressed, squeezing them a few times to relax. When using, don't squeeze too hard at once if you're a beginner, as it may cause discomfort. Also, avoid dropping them on hard surfaces to prevent damage to the spring coil. To maintain them, keep them in a dry place and wipe the foam handles with a clean, dry cloth occasionally. This will help keep the grips in good condition for a long time.
