Strength training is really bad.
If you focus training on one specific region of your body or one specific pattern of exercises you might develop strength imbalance.
Developing more muscle strength in one region compared to the opposite region is called strength imbalance.
PUSH muscles strength Vs. PULL muscles strength
Men always want to develop chest and biceps; they regularly will miss their leg day. Excessive focus on push muscles training and lack of pull muscles training will lead to rounded shoulders.
The strength ratio between chest and latissimus muscle should be 1:1. If you are able to bench press 60kg, you should be able to do 50-60kg bend over row. If you are able to do 30 push ups you should be able to do at least 10 pull-ups.
Scientific evidence supports that most of the shoulder injuries and dysfunctions are caused by a strength imbalance between the Chest (Pectoral) and Back (latissimus Dorsi) muscle.
In lower body, Strength ratio between Quadriceps and Hamstrings should be 1:1. The cause of your Knee pain or hamstrings injury could be your strength imbalance.
UPPER body strength Vs. LOWER body strength
The upper body strength should be at least 40-60% of your lower body strength.
In many gyms, the reason why we happen to see people who have Popeye upper body and giraffe legs is that they simply neglected their lower body strength training. Their basement is weak (Lol).
75% of the lean mass is in the lower body. Lower body strength training will trigger the release of growth and testosterone hormones that are essential for the repair, growth and function of each and every cell.
RIGHT side strength Vs. LEFT side strength
Very few people are ambidextrous. They can exert equal amount of strength on their right and left side.
Most of us are inherently weak in our non-dominant side. Moreover we, at any given situation prefer to use our dominant side to get the job done. So our non-dominant side is not well trained.
When you do barbell bench press or overhead press you could have missed to notice the strength deficiency between your right and left side.
- Single Arm Dumbbell Chest Press
- Single Arm Dumbbell Shoulder Press
You will be surprised and disappointed about not being able to push easily on your non-dominant side like your dominant side.
This unaddressed or neglected strength deficiency will be a cause for an injury on the left side shoulder for a right-hander.
In a nutshell, if your exercise program is not well balanced and integrated, strength training will lead to joint injuries, poor posture and poor appearance.
