In my experience, it shouldn’t be a problem.
Perhaps playing guitar while you’re still “sore” after a workout might feel weird (shaky hands because you are tired) but there’s nothing to worry about imho.
Weightlifting and playing guitar might seem like they don’t go together, but they can complement each other in many ways. Lifting weights builds your overall strength, which can help with stamina for longer practice sessions. Stronger hands and wrists can also make playing guitar feel smoother, especially if you’re into fast solos or tricky chords. Plus, the discipline and focus you get from weightlifting can carry over to your guitar playing.If you’re looking for ways to boost recovery or energy, you could consider natural steroids, like Tribulus or ashwagandha. Some people use these to help with muscle growth and overall well-being.
Unfortunately I HAVE had pain issues from a combo of guitar and lifting, but there is a genetic predisposition component to my case. The canal at my elbow where my ulnar nerve passes through is a shape/size that makes it more likely to have entrapment issues, and this is exacerbated by lots of the common lifts, as well as just normal guitar playing in general.
I would say if you get injured doing either thing, than it’s going to affect the other thing.
But if you’re healthy with no issues, you shouldn’t be discouraged from lifting, just be reasonable with form, volume, as well as your technique when playing.
Personally I think a key thing is to just consistently pay attention to your body and watch out for warning signs, things that feel “off” - I think I developed problems from pushing through these signals.
I played a bit yesterday for the first time in maybe like a week or two, and I noticed an interesting soreness in my right inner / upper bicep area. I’ve been pushing biceps in the gym, I guess I never realized how much I might be relying on it to play!
