Dumbbell upper body strength in 40 minutes: four circuits for chest, back, shoulders, biceps and triceps, with slow reps and burnouts.
Day 12 of HR12WEEK 5.0 works the chest, back, shoulders, biceps and triceps through four strength circuits, each run as 40 seconds of work and 20 seconds of rest for two rounds. Slow-motion movements increase time under tension, and burnouts push toward muscle failure. After a warm-up, the video runs about 43 minutes in total.
Collections
Equipment setup
Who Is It For?
Intermediate lifters with light, medium and heavy dumbbells and a mat who want a thorough upper body burn.
Who Is It Not For?
Not ideal for beginners or without a few pairs of dumbbells, since the circuits rely on loaded sets taken to muscle failure.
Key Benefits
Builds upper body strength and muscle across the chest, back, shoulders and arms, with slow reps that increase time under tension.
Things to Keep in Mind
Pick weights that let you keep good form near failure, and ease off the pressing and push-up moves if your shoulders or wrists feel strained.
