I use headphones at the gym, never on the trails- BUT I don't sing laugh

strength train

squats 5/3/1+/10, bench 5/3/1+/10, pull-ups 3x10, dips 3x30, core

pleasantly surprised myself; I thought I was getting very close to plateauing on my squats/bench, on my 1+ hit 6 reps on my squats and 5 on my bench, so I'm still pushing full steam ahead! smile
