Different variations change the load on different muscles. SLDL's really target the hams and take most, if not all the quad out of the equation where as a standard dead you hit the hams, gluets, and quads.
Yeah like Quick mentioned the different variations just hit different areas. SLDL is probably my favorite hamstring/low back exercise I don't go very heavy but it's an extremely effective exercise. Regular deads hit more where the SLDL is more of an isolation move relatively speaking.
I always keep a slight bend in my knees while doing SLDL.
I have been doing research on the internet on the sumo and regular deadlifts, and I have decided that for me, the sumo DL fits my body better. Yes, regular deadlifts do target the back more than the sumo, however, the target muscle for sumo dl's is still the Erector Spinae. The sumo DL uses more leg muscles than the regular DL but there is less ROM with the sumo, and from personal experience with how my body reacts to both exercises, the sumo is best for me. I also found on the internet that the Sumo DL can be better for taller people. Therefore, I will be replacing the regular DL in my workout with the Sumo DL.
