The SMAI Figure 8 loops are a heavy lifters best friend, without them a lot of lifters would be left with ripped up callouses and failed attempts at their max 1RM. These loops are made from webbing with a neoprene patch lining for added comfort have so many features allowing;
For the user to hold a heavier weight than usual for a longer period of time
Protection for hands and wrists from pain or abrasion
For those that don’t have the full range of motion to front squat (strapping to the bar used as an extension to the wrists)
The benefit to the figure 8 loops as opposed to the basic lifting straps is the ease of not having to wrap the straps around the bar and pulling tight making it a quicker process.
