Your question – “Is this kind of training beneficial?”
My questions in return:
1) What are your goals?
2) What is your current fitness routine? (i.e. Distance & duration of run/cycling; gym routine & weights, etc)
The reason I ask is because the more “in line” your goal(s) and training routine are to one another, the more benefit you will see from the effort you put into training.
If you can shed more light on the above it’ll give us have a better sense of where you’re at and where you want to go 🙂
