The majority of men are not smart but hard workers. Spending hours in the gym is of no use when your method is secretly working against you. Minor errors in normal movements restrict the muscle development, growth in stall strength and subject the joints to loads that they were not designed to bear. The same mistakes are replicated by the trainers on every gym floor. Fix them and your results will change quicker than any new program or supplement could.
Squatting with Caved-in Knees

In drifting of the knees under pressure, the glutes close down and the ligaments do the damage. Extend your knees and align them with toes and tighten your core and then hinge down, holding your chest tall in each rep.
Bench Pressing with Flared Elbows

Shoulder at 90 degree destroys the shoulder joint and restricts the activation of the chest. Bend them 45-75 degrees to your body. Your shoulders will be healthier and your chest will develop in the proper manner.
Rounding The Lower Back on Deadlifts

One of the most hazardous positions in the gym is a rounded lumbar spine when under load. Keep the bar near your body, hinge at hips, stiffen your core and pull using your lats. Every time it is the neutral spine.
Arching the Back on Overhead Press

The lower back then takes over and the shoulders cease to work when the weight becomes heavy. Press down with your butt, tighten your abs and push right up. When you cannot hold up, you have too much weight–take it off.
Swinging Through Pull-ups

Momentum propels you up the bar but your lats hardly do the job. Begin in a dead hang and pull the elbows down and back and manage the drop. Ten reps clean will be more powerful than thirty sloppy reps will ever be.
Ego Curling on Bicep Curls

The rear swing, the hips are rocking, the bicep is scarcely involved. Keep your elbows close to your body, move with as much motion as you can and rest at the top. Reduce weight by 30 percent, and you will notice the difference immediately.
Cutting Squat Depth Short

Quarter squats are heavy but do not train much. Stops above parallel eliminates glute and hamstring activity. Perform mobility exercises in case of depth and invest in at least parallel on each repetition. Your legs will increase and your knees will support better.
Rushing The Tempo on Every Lift

Fast, bouncy reps use momentum instead of muscle. Reduce the lowering to 3 seconds in any exercise and you will be struck at once by the difference in muscle tension. Always controlled reps are better than rushed ones.
Skipping Full Range of Motion on Chest Flyes

Flyes that are small and jerky have almost no effect on developing the chest. The deep well in the bottom is where the actual stimulus resides. Hold your arms open, load the chest, squeeze your top. Allow the weight to be controlled by the muscle, not vice versa.
Head Jutting Forward on Rows

When the pull is taken over by the lower back, the neck protrudes. Keep the head straight, push your elbows back and complete with a squeeze of the shoulder blades. When you are fully rocking your upper body to get through the rep, then the weight is in control.
Never Bracing the Core

Any compound lift has a loose core and this directs the force to your spine and bones. Prior to each heavy rep, squat, deadlift, press, row, inhale deeply, stiffen your abs and maintain that tension throughout the exercise. This single habit will safeguard your back and enhance any lift instantly.
