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 more 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.
