Ending strong with 2 sets of 25 weighted pushups (5lb), aiming to crush the second set without breaks. Then, side plank dips (6 reps each side, 2 sets) and weighted sit-ups (20 reps, 2 sets) keep the midsection on fire. I wrap with bicep curls using a 15lb dumbbell, holding one arm in flex while curling the other (10 reps per side, 2 sets). Another step in the challenge, another win for discipline.
