Upon starting a regular fitness routine, there are a few important accessories that will help make your workout a little easier and keep you injury free. One of the first things I added to my own collection were a pair of weightlifting gloves.
Gloves for a better grip
Gloves help improve grip and protect the hands. There are many different styles and pricing varies, so you can spend anywhere from $8-$50. It's probably best to try on a few pairs before buying. Personally, I prefer low profile gloves with very little wrist restriction and a simple design. Make sure the gloves fit snug when you buy them because with use over time, they will stretch out a bit.

Your Shoes
Shoes are often an overlooked aspect of your workout attire. When squatting and dead lifting, you want thin soled shoes that aren't too clumsy and inflexible. I like the low profile design of Adidas and Puma racing shoes because they offer perfect support for what I do in the gym. If you have flat feet or high arches, seriously consider using arch supports because it will affect your gait and foot position specifically during lower body exercise. This can make or break a workout.

Weightlifting Belt
The weightlifting belt is mainly for advanced lifters and not necessary for everyone. It is most important during heavy squats and dead lifts and will help protect the low back and ensure perfect posture during a lift. There is also a theory that wearing the belt during these heavy lifts will keep the waist small because the core is used to a degree during squats and dead lifts, the oblique muscles get larger and give the waist a wide, blocky look.

OTHER ACCESSORIES TO CONSIDER...

A Heart Rate Monitor
I was never much of a believer in using a heart rate monitor while working out, but after giving it a chance and getting great results in the process- I am now a big fan. I recommend the type of monitor that you wear as a watch and has the accompanying strap that fits around the torso, just under the chest. There are cheaper styles, but none seem to be as accurate as this type.

Weightlifting Wrist Straps
Lifting straps fit around the wrist and then attach to a very heavy barbell or dumbbell for better support and more grip strength during a lift. Personally, I don't care for them and although I own a pair, I never use them. I have found them to be too cumbersome and actually hinder my grip quite a bit. I recommend strengthening your hands and forearms with different exercises to improve your grip strength instead of depending on this crutch. But give them a try before discounting them completely, because some people swear by them. I just haven't been able to find a real use for them.
