Short-term exercise that strengthens the whole body

Typical movements such as crunches and squats focus only on bending, which misses out on many aspects of building strength and stability, however, a mixture of unconventional but effective movements will strengthen the abdominal and back muscles.

"The variation of lifting dumbbells with the right arm and then the left arm builds the muscles of the back," says Andy Spear, author of The Anarchy Abs Workout, an online program for men who want to build abs.

The exercise consists of four movements:

bend the upper body so that it becomes horizontal with the surface, holding a dumbbell in each hand and lifting them up and down,

with your right leg and left hand, resting on the floor, lift the dumbbell with your right hand, then repeat the movements, but this time lifting the dumbbell with your left hand

alternately lifting dumbbells with hands in a bent position,

take a "wide grip".

Each of these movements is performed for 40 seconds, followed by 20 seconds of rest. That's one round, from three to five that should be repeated, reports klix.ba.
