I'm just waiting for her IG to be flooded by people telling her to slow down the workouts and take a day off at the very least? GF isn't helping her body, and when she gets older she's going to feel every single ache and pain from obsessively working out in her 20's... I danced from about the age of 3 (mom thought ballet was a good idea) until about 25. It was a 6 day a week, 3/4 hours a day thing from 12 to 25. Many years later I suffer major ankle pain (I tore the ligaments in my right ankle three times, and my left knee twice), as well as lower back, and tendon pain because I didn't stop. Its manageable pain (I don't take pain meds), but I still live with it daily, and that's not fun.
I wish someone would have told me to let my body rest, heal and get stronger before going so hard again.
