I feel your pain. I had to train my legs for almost 6 months without the squat rack. You can still squat with the smith machine, but the variation/form will be different from the free weight squat, and of course the free weight squat has better "effectivity" compared to smith machine. Both have their own goods.

Here's what I did , I used the smith machine on the early stage . Then , I "made" my own squat rack. You know those weight-hangers ? I placed them in the proper width (to support the babell) and some equal weights on both side (so that they won't fall to one side or the other). Works as good as a squat rack , but with a risk of course, it's dangerous lol ( had my fair share of embarrassment before).

PS: Don't do it lol. If you want to , why not

Honestly, I have no say in this . since I've never done this variation of squats before . Heck I didn't even know this exercise even exist lol

Squats and Deadlift ? Overhead presses ? Weighted dips and pull ups? (Bodyweight/weighted)

I'm waiting for DL to appear :/ I know he's lurking here somewhere !

They do have a 1 week trial , but it's really vague , it really depends on how you and the salesperson make a deal . It can be 1 month, maybe even a few days lol .

There's something called the Bulgarian Method covered by Omarisuf, it's mostly squatting everyday. I don't think this is the same as the original Bulgarian system though.

Yup, heard of it. But have never tried neither of these programs, Im too much of a pussy to do it lol
