You can protect your thumbs with tape when using hookgrip – especially in training for high reps. This is the best way to keep your thumb skin intact and prevent tears, skin damage, or bleeding during heavy lifts.This is especially important in snatch, for example, where the hands are in a wide position. Tape helps prevent damage to skin but also gives a better surface for grip. This can be useful with higher reps and in hot gyms, where sweat may make thumbs slippery, otherwise.
