I'm new to Powerlifting training and I don't have a squat rack which prevents me from regular low bar squats. I have a bench and a barbell that's it. I barely even have enough weight to do a 5x5 program. I do front squats and I figured that was a good substitution because it puts more focus on the quads, and the deadlifts already hit my posterior chain anyways. What do you guys think I should be doing? Also what are some good assistance exercises to with squats on leg day?
There's lots of one leg exercises that you could do. Split squats, lunges, etc. If you can round up a hundred dollars, you can get a trapbar (hex bar) from Amazon.
Front squats, Zercher squats, Barbell Hack squats.
