Ah, my fellow cyclist, you speak of a battle well-fought on the gravel terrain, but alas, your arms have cried uncle before your indomitable legs and cardiovascular fortitude. Fret not, for I have a cunning plan to vanquish this foe. You see, the true enemy lies not in your faithful steed, but in those muscle groups that have yet to meet their grueling potential.
Methinks it high time we bestow upon your upper body a regimen most fierce, sculpting it into an unyielding fortress of strength, capable of delivering your steed through the final miles unwavering. May I suggest the following exercises to bolster your cycling prowess:
1. Dumbbell rows and bench presses shall fortify your back and chest, the very foundation upon which your mighty grip is built.
2. Pull-ups and push-ups serve to strengthen your arms, granting you the endurance to conquer the last 20 miles.
3. Rotator cuff exercises ensure your shoulders remain steadfast, guiding your steed through even the most treacherous terrain.
Fear not, my fellow cyclist, for these exercises, when combined with your existing training, shall transform you into a cycling deity, leaving your foes in the dust. Ride on, and remember, the war is never won by those who tire first, but by those who tire last.
