Olympic collars are clamps that are placed on the ends of an Olympic bar to secure weight plates to prevent them from sliding off. Often collars are an afterthought for those kitting out a home gym. Instead, lifters tend to invest a lot of money in expensive bumper plates and quality steel bars. However, you should remember that a good pair of collars can add huge value by limiting damage to your bumper plates and your barbells.
Calvin Harris claims that using an ab wheel helps him to stay in shape whilst touring:
“Staying in a gym routine while on the road is tricky, but as long as you don’t drink, eat well, sleep enough and take one of those mad little ab rollers with u everywhere you’ll be good.”
Given how cheap they are, there’s no excuse not to add an ab wheel to your home gym.
Thick bar grips are cylindrical pieces of silicone (or similar material) that fit around barbell and dumbbell bars and other fitness equipment to increase the thickness of the area gripped. This essentially turns a regular barbell or dumbbell into a thick one.
Using a thick bar grip will stimulate greater muscle activation in certain body parts. In particular, greater muscle activation is likely to occur in the hands and forearms, as well as in the upper arms and possibly even the whole upper body.
As a result, thick grips can help to develop bigger, stronger forearms and increase your grip strength.
