Locate the seam on the inside of your shorts or strap. It will be located on the front, near the top of the waist. Use 2 fingers on your nondominant hand to open the slot. Slide the cup down through the opening until it's fitted in the bottom of the pocket. The gel lining may make it kind of difficult to push it all the way down. Wiggle the cup back and forth until it slides all the way down if it sticks. With your underwear on, spread the elastic band out and slide your right leg through the band and the hoop on the right. Slide your left leg through the band the hoop on the left. Pull the waistband up and let the elastic bands slide up your legs. Once the waistband is on your waistline, reach behind your thighs and adjust the elastic bands until they're comfortable. If you're new to wearing a cup, you'll probably feel more comfortable if you're wearing boxer shorts underneath. With your underwear on, slide your right leg through the hole on the right. Put your left leg through the hole on your left. Pull the compression shorts up to your waistline so that they're comfortable. If you really want to, you can wear compression shorts without your underwear. Most people wear underwear though. Adjust your cup so that you're comfortable and protected. Your genitals need to be entirely covered by the cup, and the bottom of the cup should rest 12 inches (2.55.1cm) underneath your testicles. Move the cup as needed until it's comfortable. Once you've got your strap or shorts on, take a few steps back and forth. Raise your knees up to your waist to see how it feels. Do a few lunges or squats to get used to the feeling of the cup. Make any adjustments as needed based on how comfortable you are. If you find your cup pinching your skin when you're wearing it, move up a size. You can wash your strap or shorts with your normal laundry. Both the jock strap and the compression shorts will absorb sweat, so don't wear your jock strap or compression shorts for multiple days in a row without washing them. Clean the athletic cup with hot water and a sponge loaded with antibacterial soap. Let it air dry after washing it.
Slide the cup down into the opening in the middle of the strap or shorts. Put a jock strap on by sliding your legs through the elastic bands. Pull compression shorts all the way up like you're putting boxers on. Adjust the cup so that your genitals are protected. Take a few steps and do some lunges to see if it's comfortable. Wash your strap or shorts and clean your cup after every use.
