You don't go to the gym to show off. As a tool every good visit to the gym can assist you in the ability to show off elsewhere, like say, the beach. Showing off at the gym will only get you injured, and then you won't be showing off anything but your stupidity, and you can do that from anywhere.

The muscles of the midsection: rectus abdominis, oblique (external, internal, and transverse), and intercostal.

Biceps Curl (Standing Barbell)
Target Muscles: Biceps brachii, Brachialis, Brachioradialis
1. Stand with your feet hip-width apart.
2. Hold a barbell with your hands shoulder width apart, palms facing forwards.
3. The bar should rest against your thighs and your arms should be fully extended.
1. Bend your elbows as you curl the bar up in a smooth arc towards your shoulders. Keep your upper arms fixed by the sides of your body.
2. Hold for a count of two; then slowly lower the bar back to the starting position.
• Do not move your upper arms or elbows at any point of the movement.
• Keep your body absolutely still- make sure you do not lean back or swing the bar up as this will strain the back and reduce the work on the biceps.
• Keep your wrists locked.
• Lower the bar under control until your' arms are fully extended shortening or' rushing the downwards phase will reduce the effectiveness of the exercise.
EZ-bar curl: Arm curls can be performed using an EZ-bar instead of a straight bar. This reduces the stress on the wrists, although it puts the biceps in a biomechanically weaker position so they receive less stimulation.
Wide grip curl: Using a grip slightly wider than shoulder width apart places more emphasis on the inner head of the biceps.
Narrow grip curl: Using a grip slightly narrower than shoulder width apart places more emphasis on the outer head of the biceps.
