Although my numbers were downright pitiful on the TM, I'll share my experience of it.
Pros: Can use for a long time of you are pretty 'in-tune' with your body(learning when to take it easy etc). Training sessions are pretty straightforward and challenging. Will give you a good indication of where you are. I got my strongest squat, bench and press on that programme.(I had a pretty serious neck injury in the summer that set me back BIG time and I'm only starting to regain some strength now)
Cons: I did it for about 8 months and actually grew to hate it. My deadlift suffered terribly due to the the volume/heavy squatting done first at every workout. The emphasis on squatting eventually wore me down a lot. My lower body was just too tired to deadlift(especially after benching/pressing) and my numbers plummeted.
Be prepared for long-ass workouts. Getting through a monday with 5x5 squats, bench and 3x5 deadlift is not easy. You are so drained that almost any assistance work is done poorly or simply gets thrown out of the window on some days. It's almost asking for imbalances due to lack of room for assistance work.
Conditioning is brutally hard cos you feel like you are about to collapse any second before you even get near your prowler/hill.
The endless repetition of the same exercisesin the same order on alternating days really got me. I know it's easily changeable but still got to me.
I never hid the fact that I hate squatting. I don't shy away from my squats but I don't exactly have the love that I do for deadlifts either. I think a lot of this has to do with SS and the TM. Squatting every single time I was in the gym(it being the first lift in every session also) really made me sick of it. I loathe it less now on 5/3/1 and actually kinda enjoy BBB squats.
Long-ass workouts. Worth mentioning again.
These are simply my experiences. Others may rip this post apart but thats just what I thought of it. Either way I hope you have good success with it.
