I want to say this again for everyone and, please take my advice. With this stuff you will want to use your brain to choose when to stop not when you feel burned. At least at first. Because you can sometimes push to ALOT more than normal. This sounds good and it is but it can thrash you if you are not careful.
I've started making sure that if after I hit my normal 100% point I dont keep going to 200 or 300% because it's really hard on the body. At least at first. Take an extra 20% and just call it a day. Even you feel like you can go forever.
Slowly move forward so you don't ruin yourself.
I pulled out my old log books and started keeping track. My endurance has gone up to levels I won't even state because it sounds ridiculous.
This IS where I can imagine someone feeling lethargic or tired afterwards because they pushed themselves to 300% of normal.
That's not the slus fault that's the users fault.
Take it slow. Increase at a reasonable, calculated pace so that it's sustainable.
The fat loss and muscle comes.
This is absolute top tier stuff.
Not to long ago it was only used by Olympic athletes and ultra high end competitors. Now we have it.
It's a powerful tool but like all powerful tools, a high powered saw for example, it requires the user to make wise decisions so they don't chop their arm off
