I think it depends on the brand of machine. I've used a lot of different ones and most are really crap. Just bio-mechanically wrong, feels awkward on your joints.
I've started mucking about with weights the last couple of months after about 7 years of doing no weights except bodyweight stuff. I've been using Freemotion Epic machines which feel really good to me. Also I've realized that a properly lubricated high quality smith machine is awesome for chest and shoulders. My goal isn't to get strong though it's just to look good so TBH I don't care about free weights. I don't do any sports and don't really have an ego so don't care about strength. Also I think some people forget that bigger muscles isn't just from hypertrophy and strength but also simply pumping them up with glycogen and water from doing lighter weight and high volume. Realistically if you're not on drugs you're not going to get spectacular results anyway so free weights is pretty much a waste of effort IMO, unless it's sport performance specific. The most you could hope for is perhaps one of the lesser doped up olympic sprinters or gymnast physiques. If you plan on doing drugs later then free weights would be more important for building a solid base.
This is typically what I do for example, basically no free weights.
workout 1
Incline smith press
Bench press machine
Fly machine (that feels correct on my shoulders, most are crap)
Pulldown machine
Cable pulldown machine with close grip row attachment
Machine rows
Seated smith machine press
Shoulder dumbell flys
Rear delt machine
Lying leg curls
Seated calf raise
workout 2
Hack squat machine
Leg press
Leg extension
Dumbell curls
Tricep pushdowns
Tricep machine (feels good man)
Hanging leg raises
3-6 sets for the bigger ones, 1-3 sets for smaller ones.
For "stabilizers" as recommended by Stuart McGill I do:
"Stirring the pot" on an exercise ball
Side planks
Bird dogs
I never go to failure
I never use a full ROM (keep tension all through rep)
I do random rep ranges, weights and sets
I feel refreshed instead of exhausted when I walk out
I add weight only when I feel it's got too easy
I try to avoid anything that creates a risk for spinal flexion.
For CV fitness I do a HIIT type workout sprinting on a track or jumping rope, and 4-6 hours a week of walking on a incline treadmill.
