This video is part of Joe Wicks's 21-day strength challenge. Day 16 focuses on shoulder exercises using dumbbells of varying weights. The workout emphasizes slow, controlled reps and longer rests between sets.
The five exercises demonstrated in the video are lateral dumbbell raises, overhead shoulder presses, frontal raises, single-arm overhead presses, and Arnold presses.
Joe Wicks uses dumbbells of approximately 8.8 lbs (4kg), 26.5 lbs (12kg), and 35.3 lbs (16kg). He uses the lighter weights for lateral raises and frontal raises, the medium weight for some overhead presses, and the heavier weights for other overhead presses. The exact weight used for each exercise is not explicitly stated for every repetition but varies based on exercise intensity.
