Honestly on r/trp - almost every post mentions the importance of lifting. Here on r/redpillwomen, I don't think the importance of fitness is stressed enough.
Fitness improves your life in so many ways, why wouldn't you?! Better posture, more confidence, better skin, better mood, better sleep, improved health, etc. I'm so sick of women I know rationalizing not hitting the gym. Inexcusable. Unless you are overcoming a major health event there is absolutely no reason not to be going to the gym at least 3 times a week.
At my gym, there is an 70yo+ woman who is on the elliptical 1 hr+ each week. There is a 90yo man that lifts weights 6 days a week!
Also - I promote going to the gym by yourself, that way you won't depend on anyone else for your motivation. It's not that hard. Overcoming cancer is hard. Overcoming a heroin addiction is hard. Going to the gym 3 days a week is not hard.
Honestly I'm sick of working at the hospital every damn day and people coming up with excuse after excuse of why they won't exercise.
