The difference between a free weight barbell squat and a "squat" on a smith machine is tremendous. In fact, due to the fixed path of the bar on a smith machine, it is almost impossible to do anything close to a real squat on it and most people end up doing quarter or half squats, leaning way back against the bar, and involving little to no posterior chain. Smith machine squats will not build as much strength or size and, as with most machines, they don't develop much neuromuscular coordination, so the strength and size you do build will be very difficult to transfer to the real world. All of this is thoroughly explained in the SS book, one of the many reasons to get it and read it if you are going to pretend to do the program.i worked with what I had thouhg as far as squats were concerned (smith machine) and so my gains my not have been so much had i been using a squat rack.
stronglifts iirc is more of an intermediate program. if you are just starting out, stick with SS set your strength goals and when you reach them, then think about converting to stonglifts.
No. Stronglifts 5x5 is a beginner routine. Although it is very similar to Starting Strength, it has more volume (5x5 instead of 3x5) and a slightly different exercise selection (rows instead of power cleans, extra ab work, etc). Because of this, it is in some ways more of a beginner routine than SS - as the weight gets heavier, the extra volume will make progress more difficult. This is why many people switch to SS after doing SL 5x5, as recommended on the SL website itself:
Stronglifts 5x5 vs Rippetoe 3x5:
"The Problem With StrongLifts 5×5. It’s more stressful. 5×5 is better to build muscle and lose fat, but is harder to recover from. You’ll stall sooner doing StrongLifts 5×5 than doing Rippetoe’s 3×5."
"Switching from StrongLifts 5×5 to Rippetoe 3×5. Do this and you’ll be able to add weight longer without having to switch to an intermediate program. You’ll also cut down on workout time at the gym."
