The dumbbell farmer's walk or carry is an exercise with roots in competitive strongman training, but which is also popular in CrossFit and functional training. It can be a challenging finisher to any workout, or work well in fat-loss circuit training or as an accessory movement to heavy lifts like the deadlift.
Benefits
Strengthens and challenges the grip, core, traps, upper back, shoulders, and legs
Serious cardiovascular challenge and calorie burn
Less complex to learn and perform properly than many other popular strength movements
Builds muscular coordination and mental toughness in addition to strength and muscle
If grip strength is a limiting factor, lifting straps can still enable you to use heavy weights
