Build a strong back and sculpt a rock-solid middle in one shot with the archer row. This ab exercise combines a staggered side plank with a dumbbell row. "As the load moves up and down, your body has to fight to resist rotation," says Gaddour. That means your entire core—lower-back muscles, obliques, rectus abdominis (also known as your six-pack muscles)—is working overtime to keep your spine stable.
In regards to weight training, use mainly compound exercises in your routine. Compound exercises involve movement at more than one joint and involve mainly major muscle groups. Bench press, squats, and dumbbell rows are all examples of compound exercises. These types of exercises stimulate more muscle fibers than isolation exercises and are more metabolically demanding.
Now you can shred your abs like a skier shreds the slopes, with the dumbbell skier swing. Gaddour took the typical form a downhill skier uses when flying down the face of a mountain, and combined it with the action of a kettlebell swing. The combination results in a superfast exercise that simultaneously torches fat, builds explosive strength, and works your entire core from your shoulders to your hips.
But instead of just trying to perform as many reps as possible, slow down and really focus on the quality of the movement—especially the eccentric, or downward motion, of the exercise, he says. “The eccentric contraction is the most important phase when sculpting any muscle.” Plus, focusing on quality over quantity will help protect your back (some experts say crunches can be potentially troublesome for guys with back issues.)
