You work out hard to look good and feel great. The benefits of moving all that weight and hours in the gym goes beyond the physical... I know we are too modest to admit it but we all love to "turn a head" or two from a cute guy/girl.
Plus, don't you love the feeling of confidence and the self esteem boost you get from moving towards your fitness goals or your ideal sculpted body?
Just as a skilled carpenter wouldn't dare showing up at the job site without his cherished power tools, why do so many lifters go to the gym without "tools" of their own to...
Make their workout easier by supporting specific muscle groups.
Increase the effectiveness of the work performed by allowing instant weight increases or rep increases.
Protect their back, knees, elbows, wrists and other vital body parts from potential injury.
Offer a little mental boost of confidence to push through that last rep.
Provide support to already injured body parts to allow a lifter to train during recovery.
