I've never done front squats before but want to add them to my dogcrapp routine. I train my legs with smith machine squats, but also want to start doing them on the free barbell. Would it be a good idea to alternate between these two lifts within my dc routine? Also, they said the 1 set of 20 reps is good for squats, does this also apply to front squats? What is a better lift for building size? My legs are small in comparison to my upper body and I want to even them up.
