I did my phase 2 test for goblet squats and ran out of dumbbells options at 50kg, where I could still do more than 3 at a guess, maybe 6-8 with the 50kg. Is there a way to do these with more weight? Or should I replace them with barbell squats, either front or back? Until this month, I hadn't trained for 6 months or more, but about a year ago, I was doing the Stronglifts 5x5 program and was at around 100kg for 5x5 barbell squats, so I guess I will get back to that sort of weight range in a month or so for squat-type exercises.
