Can muscles tighten and give you limited mobility if you work them out and don't stretch after?

[MichelleJustAsking]

I went rock climbing for the first time a couple of weeks ago, and definitely ended using muscles in my body that I had no idea existed. I also have a fused spine, so I'm sure those muscles in my back have atrophied and combined with my limited mobility, I had to compensate my movements.

I am noticing that the outside edge of my arms (like right by my underarms) are SUPER tight and sore STILL... and it almost seems that I don't have the normal range of motion I used to have with my arms. Even something as simple as trying to stretch by bending my arm and putting behind my head/pulling gently on my elbow, is excruciating. It's just super tight. It's an equal pain on both sides, so I'm pretty confident I didn't injure one of my arms.

Could this be caused by not stretching after climbing or does it sound like something more serious?

No, its a normal reaction. It will go away. When you climb, you use different muscles and you use them in a different way. And climbing seems relaxing and slow, but the muscles remain statically flexed the whole time. Next time, do a good warm-up. Start with the big muscles and then the small ones and start with easy routes. At the end, cool down by climbing a few easy ones

It sounds like your muscles are still being rebuilt after the strenuous climb. That is normal when using not oft used muscles. You need to do some cardio and that will help flush the lactic acid from your system and reduce the soreness. A few more days and you'll be fine.

Oh and eat a banana. You need potassium.

if you don't stretch everyday but gain more muscle mass you will lose more and more mobility as you progress. but all you need to do is stretch everyday and you'll be fine. i forgot his name but there's this body builder, huge guy, he stretches everyday and he's more flexible than i am.

Your triceps must have gotten an good ass workout :,)

Static stretching is what you need (if it's pain) don't do any too hard on triceps.

Do the tricep static stretching after the lactic acid dwells down.

And yeah muscular tightness can fuck up anyone's mobility:P

Sounds like u may have pulled the muscle, strained it or something. I weight train a lot at high weights and I only ever get a soreness for up to 5 days after and that's only after leg day

We call it "getting stiff".
