Improving your bending ability is crucial for more than just preventing injury. In fact, flexibility training is an important aspect of gaining strength and size. The typical lifter spends most of their day outside of the gym hunched forward over a computer further deteriorating any chance at proper posture. Outside of just preventing injury, having better posture helps to show off the muscular physique you worked so hard to build. Proper flexibility also goes hand in hand with full range of motion exercises like squats and deadlifts, which are major muscle builders. Having tight hips and shoulders can inhibit proper form and limit your fitness, so get to work on getting flexible.
