For me the biggest problem is: strength-training 3 to 4x a week I've started that multiple times last couple of years. But it's difficult to stay consistent. Not because of will power, but because: - Illness -> sometimes you get ill, and don't have energy for a few days and the weeks around it - Busy/full agenda -> some weeks I'm swamped, and don't have the time, energy or rest in my head for doing exercises - strength training is heavy! -> Sounds ridiculous, but when I started with strength training, everything is fun, new and with every success I'm very proud. But after a couple of weeks, I'm adding more and more weight on my dumbbells, what makes it harder to do the exercises. And the resistance to do them grows. An easy solution is probably not adding weight too soon. But then it's too easy. I also have to deal with better/stronger weeks, and weaker and low-energy weeks. Having 3 young children doesn't help in this at al 😅 So if you have a solution to grow muscles quickly, without being/getting it too heavy, I'm all in 🙃
