How to Flex Lats

Flexing your lats is an important part of posing during a bodybuilding competition. Doing it correctly allows you to demonstrate the development of your muscles and show off your proportions and the symmetry of your figure. It can also help you stretch out before or after a workout. To flex your lats, start with some relaxed poses before moving into more complex ones. Make sure you stop posing if you feel pain, as you don't want to accidentally cause strain.

Learn how to isolate your lats when flexing. Your lats are a pair of wide muscles that run from your armpits to your lower spine, wrapping around the back of your ribcage just beneath your shoulder blades. To figure out how to isolate your lats, first stand with your feet together. Arch your lower back so that your chest is pushed forward and your butt is pushed out. Spread your upper back by lifting your arms slightly away from your sides and holding your hands about 6 inches (15 cm) in front of your hips. Push your shoulders back and tense the muscles in your armpits.^{[1]XResearch source}
- As you get into position, imagine that you are holding a small ball in place under your arm with your muscles, while also holding your elbows up slightly.

Use a mirror for guidance. When flexing at home or at the gym, stand in a front of a mirror. A mirror can help you make sure you're mastering the moves correctly. Watch your body closely as you shift positions to ensure you're flexing correctly.
- You can also have a friend take pictures while you flex, which you can later review.

Flex your lats from the front. The front pose is a relaxed pose you can start with when flexing your lats. Press your feet firmly against the floor to stretch your upper quad. Pull your lats upward and flex them as widely as you can by arching your upper back and pushing your chest forward. You should feel your shoulder blades pushing into your back. Keep your arms relaxed and held at either side^{[2]XTrustworthy SourceCleveland ClinicEducational website from one of the world's leading hospitalsGo to source}

It can be hard to utilize your lats, especially if you're new to flexing. Seek out the help of a professional trainer. If your gym provides trainers to members, take advantage of this. You can also look up trainers online.
There's always a risk of injury if you're engaging in new workouts, flexes, or poses. If you feel strain at any point, stop what you're doing. Flexing past the point of pain can cause injury.
