Review of The Element Sissy Squat Machine.This is a great addition to any gym, home or commercial. It is super compact & weights around 45 lbs. It is about 3 feet long, 2 feet wide & 2 feet tall. Despite its small size it is incredibly stable even on a client I have that is 6'4" & 300 pounds. It is very adjustable for almost any size. It adjust very easily & quickly.This machine will help you achieve a near perfect freestanding squat by keeping your legs perfectly vertical. This will isolate the Quads better than even the Leg Extension & much safer on the knees when done in a slow cadence, IMHO. This will keep the Hamstrings, Glutes & etc as just stabilizing muscles allowing the Quads to do the brunt of the work for great intensity.Body weight squats can be done with great intensity with going at a slow cadence of around 5 seconds on the down(Negative) & 5 seconds on the up(Positive).By adding weights like a weight plate, dumbbells or a weight vest you can add even more intensity.Also, the level you go down can also increase the intensity. If you go below parallel & go ATG(@ss To Ground)this is amazing on the glutes as well as the quads. You can even go back further & come back up for a great crunch. This will torch the whole core area.As with anything of a physical nature if you have any medical conditions get clearance from a doctor. If you have knee issues I would recommend you proceed with caution & only try partial squats with assistance. More advanced movements should only be tried after the basics are perfected.This machine is well worth the money. It will blast your Quads like almost nothing else.To your long term health & fitness,Mark
