I hope I didn't sound entirely unsympathetic. I understand the frustration. I work out with my trainer in the fitness room used by the US Marshals. There's one woman who's often down there who is SO strong. It's really easy for me to get in a funk when I see her lifting 3x as much as me. But she's also been doing this for years. Now I could be wrong, but I think she's mostly just a gym person, so I bet I could show her a thing or two on a road or mountain bike or in a yoga class. At least that's what I tell myself.
I could get stronger if I was willing to add another strength day into my routine, but there's just not enough room in my schedule at the moment. I've been trying to do some stuff with free weights at home.
I do think you should focus on the positive Catrin and appreciate that if you work at your upper body strength, it will likely get better over time. Just don't stubborn yourself into an overuse injury. I, personally, have to recognize that I can only do so much. I could ask my trainer to really kill me each week, but it would then impact my ability to do other things. Balance, balance, balance.
Speaking of balance, make sure you work on that, too!
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
