The chest is one of the most usually trained muscle groups of the body. Aside from it boosts a person’s overall strength, a well defined chest signals power, toughness, and masculinity. The barbell bench press and the dumbbell bench press are two of the most known exercises for the chest. However, some people prefer doing the former while others choose to do the latter.
According to Muscle and Fitness, doing the barbell bench press needs a wide, fixed hand placement on the bar, so bringing the hands together at the top of the movement is improbable. In comparison, dumbbell bench press entails the hands to move freely. The fixed position of the hands in the former activates the upper pectoralis (pecs) and the front deltoid while the free movement of the arms in the latter allows the involvement of the lower pecs.
As per the publication, a study with 10 trained athletes was conducted to study muscle activation using EMG analysis. The variables measured were the muscle activity in the both the upper and lower pecs and the front deltoids. The athletes were tasked to do both the types of bench press bench using 75 percent of their one-repetition max (1RM) for four repetitions.
The study found that the barbell bench press activated the upper pecs and the front delts as compared to the dumbbell version. Also, the latter, engaged the lower pecs to a certain point.
Iron Master cited some comparisons between the barbell press and the dumbbell press in terms of range of motion, symmetrical development, and muscular tension.
When it comes to range of motion, the barbell press does not allow the arms to move in to their full range of motion, as the hands are locked in a single motion on the bar. This restricts the possible extension of the arms; thus, it affects the press’ total movement. In contrary, the dumbbell press allows an increased range of motion, since it requires both the hands and arms to lift the dumbbell and extend the movement. Furthermore, the latter engages more muscle groups and puts more tension from the press.
In terms of symmetrical development, the barbell press may involve hand dominance at times. As per the publication, a person may have muscle size and growth imbalance, it he performs the bench press while favoring one side. On the other hand, the dumbbell press lets each arm have its own weight to press, since each moves separately to lift the weight. Thus, the latter provides equal work and development.
With regard the tension in the muscles, lifters tend to slide their hands outward during a barbell press,.to pass on the tension to other muscle groups. This practice can adversely affect a person’s result, as the tension that is supposed to be placed on the chest muscles is reduced. Meanwhile, lifters can control the movement of their arms in a dumbbell press, which preserves the motion in front of the body and not outwards. Thus, the person will be able to maximize the tension on his chest muscles for a longer period of time, optimizing the results of the press.
As per T-Nation, dumbbells are the best and most versatile when it come’s to the body’s response to chest exercises. In addition, they are viewed as safer and have less risk of joint injuries, as compared to the barbell press. Also, the dumbbell press can remove all other movements elicited in performing the barbell press like excessive chest arch and legs driven on the ground.
Overall, while they are executed differently, dumbbell bench press and barbell bench press are both capable of boosting the mass and size of the chest. They also have separate benefits to the chest; thus, doing them both is assumed to boost overall chest development.

Alcohol causes significant harm to those other than the drinker: Study
People who are in close proximity or connection with alcoholics can experience harm because of their drinking, according to a study led by an Indian-origin scientist.
According to the research, published in the Journal of Studies on Alcohol and Drugs, an estimated 53 million adults in the US experienced harm because of someone else’s drinking in the last 12 months.
Researchers led by Madhabika B Nayak of the Alcohol Research Group in the US analysed data of 8,750 adults who answered questions from two databases in 2015 — the National Alcohol’s Harm to Others Survey and the National Alcohol Survey.
They found that some 21 per cent of women and 23 per cent of men experienced harm because of someone else’s drinking.
These harms included threats or harassment, vandalism, physical aggression, harms related to driving, or financial or family problems, according to the study.
The specific types of harm experienced differed by gender. Women were more likely to report financial and family problems, whereas ruined property, vandalism, and physical aggression were more likely to be reported by men.
There is “considerable risk for women from heavy, often male, drinkers in the household and, for men, from drinkers outside their family,” the researchers said.
Additional factors, including age and the person’s own drinking, were also important.
People below 25 had a higher risk of experiencing harm from someone else’s drinking. Further, almost half of men and women who themselves were heavy drinkers said they had been harmed by someone else’s drinking, the study stated.
Even people who drank but not heavily were at two to three times the risk of harassment, threats, and driving-related harm compared with abstainers.
Heavy drinking was defined as drinking five or more drinks at a time for men or four or more drinks for women at least monthly.
“Control policies, such as alcohol pricing, taxation, reduced availability, and restricting advertising, may be the most effective ways to reduce not only alcohol consumption but also alcohol’s harm to persons other than the drinker,” Nayak said.
Ditch the difficult diet for healthy living
Fitness is very important. But any drastic change you make in your lifestyle will not be sustainable.
According to celebrity nutritionist Pooja Makhija, it is important to give up a difficult eating pattern as a difficult diet will not help.
“If you need to make permanent change, small tweaks will help you attain the goal. Only small tweaks and lifestyle hack will actually show the change. Keeping in mind the basic diet and healthy eating habits will help. Eating less doesn’t help but eating right does,” added Makhija, who came in support of the anthology “Healthy Binge” which will air in June on Sony BBC Earth.
She has shared some basic fitness tips:
- Never eat large meals in large gaps. Eat every 2 hours and in small quantities.
- Don’t do extreme physical activity. Do timely exercise and periodically.
- Never compromise on eating as it differs from person to person. The quality of the food is extremely important but the quantity is not.
- Consume water. Eating food is important but ignoring water will ruin all the efforts. Having water time to time is very important for the proper working of your body.
- Having a balanced diet is extremely important. Don’t go with trends but learn to eat balanced food that will help in the long run.
At the moment, she is working on her third book which “describes what to eat and what not to because a millennial should know their diet at very early stage”.
