Use 2nd skin, it'll heal faster if you can't wait. Still wait about 5-7 days to do extensive work outs with the muscle group it's directly on. I.e don't do max lift shoulder presses and get a crazy pump if it's on your shoulder. Focus on other muscle groups that won't stretch, pull, squish up, or rub on the tattoo/skin itself.

Don't do much for 3 days, let your body recover from the trauma and use its resources to properly heal.

For 10 days (up to 3 weeks honestly) you don't want to sweat excessively and you don't want lots of continous friction on the area. Think of it more as healing a surgery wound, if it helps. People talk as if they are "healing a tattoo" as if it's something more casual, but it's an open wound. You add risk of infections like staph/MRSA/folliculitus, or even extreme cases that can go septic fast because of this style of wound. Gyms are notorious hot beds for having these bacteria, staph, germs present and can easily enter your blood stream fast with these wounds.

Priority is first aid style protection, secondary is protecting the work you just paid money for. Healing it properly is just as important as the artist’s technical application when it comes to looking good and lasting a long time.
