@joellemarie197 I started doing getups and swings in early 2015 and then started doing S&S by the book in early 2016, pretty much 5-7 days per week up until November 2017 or so. I eventually got up to doing it with 40kg but I never really timed myself and was never in a huge rush. I did timeless before timeless was codified. At my peak, I probably could have done 48kg, at least for a little bit. 40kg getups were pretty strong. However, I didn't want to buy a 48kg bell. I would have been 30-33 between when I first started with swings and getups to when I transitioned away from S&S. I switched over to Karen's Smith's Refine after that but there were still days where I would do a S&S session.
I thought the results were pretty good, but I think I went in with rather reasonable expectations. I didn't have any pain, I didn't have any soreness. I was never banged up. Doing the program every day became routine. It wasn't fun, it wasn't exciting, but it was a pretty effective dose for what it was. I was both stronger and more conditioned. I really liked the mental aspect of it where I knew where I was at any point in the session, and thus also mentally knew when I was at the half way point, or 3/4 point, or nearly finished.
Most of the time I was doing it with just a single 32kg bell, that was really nice. Knowing I didn't need anything else. I also really liked Refine, but I didn't have enough bells for everything. I had a 10kg, 12kg, 16kg, 20kg x2, 28kg, 32kg, 40kg. There where drills where I wish I had a second 16kg, and a second 32kg, and a second 40kg, and 48kg x 2 (Dead lifing, I am no way strong enough to press, swing, and probably even squat a pair of 48s). The only needing one or two bells for everything was a HUGE plus.
But like I said, you need to have fairly reasonable expectations. You are not going to S&S your way to the Olympics. I had the mentality that I wanted to be able to do a session and have it feel pretty easy, with the mentality that there probably isn't much in every day life that is going to rival it in terms of short term physical difficulty. Anything in day to day life that would still be physically challenging would probably be some super long duration thing. I also had the mentality that the movements should almost be performance like and should be deliberately beautiful. No flopping on the ground for a getup or wimpy half ass swings. Poor movement is its own form of weakness. If your getup looks like absolute shit, the weight doesn't matter so much.
I would say the program is very good for what it is, and it has a lot to offer to someone new. It allows you to focus all your mental energy on doing just two things very well vs trying to learn 6-12 new things. Its a great place to start for someone fresh, who can make a daily effort and focus on gradual progress over months or even years. I remember several years ago a woman in her 40s posted in here how she got S&S and started it with 8kg and just did it every day, gradually going up 4kg until I think she got up to the women's simple standard. It was just a morning 20-30 minute routine she did every day. She worked in an office and was not a gym rat but they had some push up contest at her work, and despite not training pushups she went and beat all the other women. Its perfect for that type of person.
If you are brand new to kettlebells, S&S gives you a clear road map to a point where you will then be good to go out and do other things. If you are new to swings, and new to getups, I would definitely recommend S&S, at least until you get up to the timeless simple standard. When i went and did Refine, all of the drills came fairly easy to me because I was building them on a foundation. The variety was much higher, every day was different.
If you want a program you can do every day for life, S&S is a pretty good option. I would not consider someone who just maintains the timeless simple to be weak and poorly conditioned. You will be stronger and better conditioned than the vast majority of people your age, especially once you get 30+. I have often said, If I could get to the point where I could maintain an 8kg or even 12kg turkish getup as an 80 year old man, that would place me physically above like 95% of other 80 year old men.
For what you are looking for, Just do these exercises every day, S&S was designed to do that. You could spend years doing it and still benefiting from it.
