This was my biggest concern as well. I don’t look at the Giant as something id run forever, but i will rotate it through my training in spurts. I’ve done it for approximately 6 months and I haven’t lost anything in my squats. I do them on my “rest day”. That’s the beauty of the program, if you’re in decent shape you can do all 3 sessions and still manage a 4th freestyle session if you want. One thing I’ve fully come to realize is the the double clean and press is not a upper body workout. It’s a full body workout. My quads, glutes, core, shoulders, and grip all get taxed. This is the strongest I’ve ever felt at the age of 35 running this program.
