According to Liz Cook Tattoos, it's important for people with new tattoos to refrain from workouts and heavy weight lifting until their skin has healed and returned to its normal texture. Strenuous physical activity causes excess moisture on the skin that can interfere with the healing process.
Along with creating excess moisture, Skin Artists Magazine explains that certain weightlifting moves can stretch and pull the skin, leading to irritation and pain. Additionally, using weightlifting machines in public gyms can spread bacteria. Skin Artists Magazine advises that people with new tattoos also avoid engaging in contact sports during the healing process to minimize the risks of skin abrasions and potential infection.
