HD has a wider wrist support and wider hand coverage. Our OG design has a thinner wrist support and more minimalist hand coverage, designed to fit the human hand. Which is better? That's purely personal preference, generally speaking bigger athletes tend to prefer the HD. Those who like less bulk on their wrist prefer the OG.

If you're experienced with this style of grip then potentially yes. However you do not need to have a lot of excess hanging over the bar like you might see some athletes do. Especially with how grippy these are, it doesn't aid in keeping you on the bar. We do not recommend sizing up as it increases the risk of getting grip locked on the bar. Sizing correctly will also reduce discomfort considerably and likely improve the longevity of your grips.

We highly recommend using without chalk, although you can still use them with chalked bars (they'll still perform the same as your typical carbon fibre/diamond fibre grip)BUT they are WAY better without. It's essentially this, if you've felt how good they can be, why would you want anything less? Keeping them clean after or before a session only takes a small wipe down with a wet cloth (or sweaty armpit, gross but effective). Most of the time if you wipe the bars they're used on they won't themselves even require any kind of wipe down or after care. If they ever feel slippery-er it probably means they're due a clean or the spot you're grabbing on the pull up bar is caked with chalk. An easy fix with our micro-towel included in your grip bag.

Almost every pull up bar out there, but may not perform as well on speal bars/zinc coated. It's mixed reviews but generally speaking cleaned down bare steel bars as a whole are okay. That being said when we say not as well, we mean how they would be on other bars. They may still perform better than you current grips. But we would still recommend our Elite Lites for chalk free steel bar work or Fibres/Base for chalked steel bars. Do not use with taped bars, doing so will void your warranty

Base is our original grip which uses a classic synthetic leather surface, they're best used with chalk and in chalky environments. Same is true of our Fibre Grips. Our Elite Grips are our specialised rubber surface which has a "omg game changer" grip surface and are chalk free.

One way you can decide is how you grab the pull up bar. Thumbs around, fingerhole may be better, Thumbs over, fingerless may be better. Especially when using for muscle ups thumb over the bar is the recommended use when completing bar muscle ups. But it does come down to personal preference. Fingerholes also offer other options such as to be used on KB's or on a barbell as needed. It's also worth noting you do not necessarily need to put your fingers all the way in the fingerholes, and just to the first knuckle will often give you more of a dowel effect to lock onto the bar with. Again test and trial and see what works best for you.

The main differences is remembering to open the hand to let go instead of sliding off the bar, 'with great grip comes great responsibility' and it's important that you remember that, what keeps you locked onto the bar is also what will stop you coming off. So a couple of things to consider:

- Always use first in a warm up setting or a skill setting first, before jumping into a workout. And certainly before competing.

- Practice letting go vs sliding off, it's a small adjustment and won't take long to feel natural

- When performing movements such as muscle ups you will need to learn to relax/open your hands at the top. Thumbs around athletes, we would recommend using finger holes as driving the thumb into the grips can cause them to tighten excessively and get grip locked. Again practice first before completing in a workout under fatigue. Small adjustments that will make the movement a lot more comfortable.

These grips will transform all of your gymnastics movements, but may need time to adjust if you're not use to just how grippy they are.

*We do not recommend using for pull overs if you're a) new to the grips and/or b) yet to achieve proficiency in this movement. Again remembering to open the hand as you rotate around is key.

Simple, wipe them down. It takes literally 15 seconds, dampen one end of your towel and wipe the sections you require, then dry with the other side, test with a grab of your hand to ensure it's dry. If you're in a team that requires chalk, keep their hand prints chalked and yours cleaned. If the bars are long generally there will people using the same chalked portions of the bar so simply move to one side and you'll be off and away Frog Maverick.
