1. Start slow and low: 
7xShovel 		
7xChurn Butter 		
7xChop Wood 		
3xFlip Lever 	
7xDrive Fence Posts 	
7xHoist Sack 	
7xTuck Bales 	
7xStoke Oven 	
7xThe Fireman 
7xChop Tree
Repeat for 5 minutes. 
For the next nine day add one minute per day.
When you reached 14 minutes add one to the number of every exercise until you reached 14 in every exercise with the exception of Flip Lever. There you should stop at 7 reps. 
After that: 
- Try to increase the numbers of reps for each movement.
- Add the movements:
            1. Degraded Beast
            2. Fertilize the Fields

Have Fun!
The slow and low approach is for people who haven't exercise for a very long time (down to never). The low number of repetitions (reps) is mainly to protect the joints from an "overload".
2. Progression tipps: 
- Alternate between days you are trying to make more reps per cycle and days you move slower per single rep.
- Mix in some other exercise-forms for 14 minutes (everything goes) 
3. Weight progression: 
Start with a weight you can make it through the initial 5 minutes with ease. Stay with ist for at least 4-6 month before even thinking about taking higher weights. I started with an 5 kg (11 pounds) hammer and kept it for 12 month. 
Weight progression ain't that important for SG, because it's more of an intervall-training. 
4. Expectations
One of the great problem with SG is: A lot of people use it with other Everyday Systems especially No S Diet. If you use SG while being on a diet you won't build much muscle mass. But you will also lose a lot less muscle mass trough the diet, which is an great asset, because you will keep losing fat with with a higher rate. 
So if you use SG with a diet: 
You will lose weight (more fat than muscles), your muscles don't grow a lot but get denser (and you will also get stronger) and may become more visible. 
You can get to this look:
If you use SG with a caloric surplus: 
You might add muscle mass, but you will also add fat.  
I wouldn't recommend SG for serious muscle-building. Not because it doesn't work, but because there are other, more efficient ways.
