A lot of people have this great idea about getting in shape, becoming healthier and what not. the problem is all the crap they are fed.
Drink this fucking protein shake, eat 6 meals a day, train HIIT, do weights, callisthenics, 3 times a week, 7 grams of protein per ounce, buy this gizmo, use this electrode belt, avoid fat etc etc.
All-of-a-sudden become fit is a research project. You need 10,000 steps a day, people that take stairs have less chance of heart disease and so on and so on.
Guess what most people do? choose the easy fucking way out. Step 1, buy this fitness device (because you'll need it with all the fitness you're gonna do right?!), step 2 follow magic formula??, step 3 get fit
Here's my "magic formula" to get fit: Move your fucking ass. Do whatever workout you want that is COMPOUND movement at the intensity you can SUSTAIN. Listen to your body, if you're feeling depleted take it easy, if you're feeling pumped put your back into it.
It's the same thing with gym memberships after the Olympics, 2-4 weeks later they never come back. No fucking gizmo is gonna lift those weights, run up that hill or do 100 burpees for you. That's you that has to do that. Do it. -remember that when you're watching other fitter people work. (You know, NFL, NBA, Olympics, they're at work)
