hey guys just wandering about tips for increasing grip/hand strength. Ive been squeezing a tennis ball in my room for a week and i already feel a huge improvement. Doing it for wrestling, because i already have top-notch tilts but i want it to where when i have hand control, they get theyre hand back when i give it to them. I also have been just digging my hands into a thing of sand and squeezing hard. So any tips would be helpfull thank you.
