People sometimes ask me where to start with their training.
There are all sorts of things out there but for the average person I think Craig Ballantyne's material is good basic stuff - strength training plus intervals.
Yes there are other things we could recommend, but for most people I think this is fine. Simple and straightforward. (His advertising copy gets a bit excessive....but the material is actually pretty good)
Here is a free (yes free...) programme from Craig for you to download.
This is Craig's 4-Week Bodyweight Program basic, but good material. Click the picture above or this link and download the pdf. Just right click and choose "Save As'
