People want results and they want them NOW!!! That's the main ideal mindset for a lot of people that believe that if they go all-out hardcore they'll immediately get results by the end of the workout or the next day and if they don't they'll call a program fake or say it doesn't work. Training for results takes time and strategy. They're lead to believe that hardcore, back breaking workouts will turn them into a god or goddess and have them drooling over the belief that if you do their "superior" system they'll be your friend but if you don't they treat you like garbage.
I get it, I don't like long workouts either, a lot of times their boring to me. That's why I personally feel that High Intensity Interval Training develops the best results in the shortest amount of time. The thing to realize is though in order to get the results, you need to put in the work; there's a reason the Intensity is in the title. You put in the highest level of effort in a short span of time that can range from 10-30 min. The other great thing is that for optimal results you only need to do them three times a week at maximum, 1-2 days minimum. This leaves you with more time to do other stuff that goes on in your life; kids, going to school, building a family, being around loved ones and so on.
Personally I believe themed workouts bring out the best in you because it creates imagination, develops creativity and YOU can make it fun. That's why I put in the Superhero Workouts. These workouts are extremely intense, no more than 25-30 min. and I get to challenge myself while having a good time. There are many ways to do HIIT; you can do them with or without equipment, they can be done as a finisher or they can be done with a single exercise such as The Burpee. One of the very best forms of this training is by doing Sprints; you run as hard as you can for 30 seconds or less either on a track, field or hill or no more than 60 seconds in place, don't need to do more than 6 to start with and do a maximum of ten. If you read the previous article on the Workout I had done which is very advanced that's another idea too. It is the system that creates the most fat burning, hits those Fast Twitch muscle fibers like nobody's business, develops insane loads of natural HGH so forget Steroid injections and you get to burn calories during and hours (sometimes days) after a workout.
I like bodyweight workouts the most when it comes to this kind of training because they can be done practically anywhere, anytime. It can be done with weights too but unless you travel or have a home gym or go to a gym it can get rather difficult. Some of my old sprint workouts lasted no more than 10 minutes since all I did was run up a hill really hard and walked back down and repeated 4-9 times. Want to see that fat melt like Margret Hamilton, have a body that looks like it was carved from granite, a metabolism that would scare the hell out of family at gatherings and what about the ability to generate levels of hormones that hit your sex drive harder than an 18 year old regardless of your age or sex? Hell of an idea huh? Do some research on it, test it out for yourself and as you get better, be able to eat the things you love and burn it off. The better you eat the higher the results but you can still build a decent level of natural muscle mass (no to be mistaken with heavy bloated bulky muscle) while on your current eating habits.
