Why are Spanish squats so hard?

[Rebecca08]

I tried regular squats and after a while in the gym I was able to do regular squats loaded with 50 kilograms (100 pounds) for 9-10 repetitions.

However, after a while I developed pain in the knee so I was suggested to do Spanish squats instead, until I heal.

I tried Spanish squats and after learning the technique I found out that I can do only 5 with my bodyweight before my quads start burning and I get a muscle failure.

The comparison is astonishing! I understand that Spanish squats are harder, but why would I go from 100 pounts 10 reps to just 5 reps with my body weight?

Damn girl, that is wild how much harder the Spanish squats are! No wonder your quads burn out so quick. Regular squats use a lot more of your bigger leg muscles so you can lift way more weight. But the Spanish squat really isolates the quadriceps muscles in the front of your legs. Since you're only using bodyweight, all the tension is right on those quads. They've gotta work a lot harder to lift you up and down without any other weight helping. I guess it makes total sense that you'd fatique faster. Don't feel bad though, those squats are no joke! At least they'll really help strengthen your quads while giving your sore knee a break. Just start with lower reps and build up your endurance over time. Those leg days will be paying off before you know it. Don't get frustrated - just listen to your body and you'll be back to regular squats before ya know it!
