Bend over and grip a pair of dumbbells and get ready for the initial deadlift. Your feet should be shoulder-width apart, back straight and head looking into the horizon. This is your starting position.
With your legs push yourself up all the way until you are standing completely straight. Then, go back down all the way until you lower the dumbbells down to about a few inches above the floor.
Finally, repeat entire movement for the desired or prescribed number of repetitions.
Perform this exercise in a smooth and fluid motion
Don't hunch your back; it will be bent over but you should not be hunched over
SPECIAL NOTES & LEVEL of DIFFICULTY VARIATIONS
To increase the level of difficulty, slow down the movement or use heavier dumbbells.
This exercise is not for complete beginners. Some previous experience with regular (barbell) deadlifts is needed.
The key to executing this exercise well is to make sure your back is not hunched over too much and that your are pushing off (the floor) sufficiently with your feet and legs. Don't lift the weight with your (lower) back too much. The deadlift is an exercise that is all-inclusive in that it engages many muscles in both your upper and lower body.
Thus, do a few practice reps with some light dumbbells until you get the feel for the movement. Then try with heavier ones.
