It’s amusing to see so many daily articles on the Internet stating what the “BEST” exercise/diet/cardio program etc. there is for losing weight, improving cardio, building bigger biceps, toning your core, getting rid of back pain, etc., etc. Nothing is ever the best for everyone, plain and simple and here’s the first, and in my opinion, the most important reason why.
When it comes to “the best”, you have to consider a few variables. At the top of the list is safety. Not only safety of the exercise itself but also the application of that exercise for each individual. For instance, the bodyweight squat is a wonderful exercise that builds 
strength in the legs, hips and core as well as provides improved mobility in the ankles, knees and hips. And when performed to muscular fatigue, it will provide significant cardiovascular stimulation. But not everyone can perform this exercise properly due to mechanical reasons or they just can’t grasp the movement and therefore, it is not a safe option for them because they can incur an injury or further along an already bad situation. On the other hand, some people can execute this movement flawlessly, but the end result for them may be something that causes a problem due to a previous issue or it invokes some discomfort in a joint that previously wasn’t there as an example.
So really, the take home message is this: not every recommendation of the BEST has a universal application to it. Proper guidance and coaching, along with common sense and not blindly following a suggestion is probably a good start in to finding what’s BEST for you.

His goal is to be progressive each work out, i.e., looking to do better than last time. The approach is simple: he will do as many reps as he can in good form, rest long enough to “almost recover” and then do more reps. He will repeat this process until 5 minutes has transpired. He will total up all his reps (or time) and notate his performance. Notation: A goal can be to perform more reps/time for the first set compared to that of the previous workout OR shoot for a higher total number of reps/time for the 5 minute period. Either way, progression and accurate record keeping are important. To reiterate, 1 exercise per day for 5 minutes. He will rotate through these exercises every 4 days. These are the 4 movements, done in this order:
