Tricep fatigue but only one arm
Disclaimer....I am 48 years old and have been a blue collar laborer my entire life. I am also right handed. So maybe my right arm is just telling me that it's a little worn out from years of strenuous work? That said I notice on longer harder rides that my right tricep tends to get fatigued. The other day I did a 55 mile gravel grind with over 4800' of elevation. It was a tough one but my right tricep started feeling like I had done 1000 one arm push ups about 35 miles in (when I started feeling the fatigue). Nothing was injured and this is typical for me. But if it was simple core conditioning or upper body conditioning (I am not in the best core shape I admit) why wouldn't both arms get fatigued? It seems as if it was hit and miss so I am wondering if it was subconcious tenseness and my dominate arm (right) was doing the most tensing up? I didn't have any other abnormal issues such as back pain or knee pain etc.......Just my tricep.
This is on a bike with bars a little above saddle height and very comfortable to ride. I have a nice upright ride with both arms slightly bent at elbow and not locked. This is on a Salsa Fargo so anyone who knows this style bike knows how they are designed for upright comfort with long headtubes and high stack height.
