Tight hip flexors can also make it harder for your glutes to activate—since they're opposing muscle groups, when one is really tight the other becomes lengthened. When a muscle is more lengthened than it should be, it takes away some of its ability to contract. When your glutes are in this compromised position, it can cause other muscles to do more work than they should, making your workouts less efficient and sometimes, increasing your risk of injury.

The irritation of the sciatic nerve causes hip and lower back pain, which spreads downwards to the limbs and feet. It is estimated that 4 out of 10 people will develop sciatica or irritation of this nerve at some point in life. The sciatic nerve is located deep in the buttock, beneath the piriformis muscle, so its constriction and swelling can also cause sciatica pain and irritations.
Keeping your hips mobile is important for overall hip function and athletic performance. Mobility refers to the ability of your joints to move through a pain-free, unrestricted range of motion. For cyclists, hip mobility is critical since pedaling occurs in one plane of motion, and after miles and miles in the saddle, hip tightness and restriction may develop. The following movements will help with hip mobility.

You're more likely to get a hip flexor injury if you've had one in the past, you don't warm up properly before engaging in athletic activity, your muscles are already tight or stiff, or your muscles are weak from being overused. If, while exercising, you try to do too much at once in too short an amount of time, you can also put yourself at risk for a hip flexor injury.
