With the plethora of fitness information on the internet, it’s difficult to find the good and cut the BS. Reading a ton of fitness blogs is only going to make you more confused about exercises and programming. Also, doing a random workout from your favorite blog may burn a ton of calories and give you a great workout, but lacking structure in your program is inferior to a program with structure. Trainer to the trainers, Nick Tumminello says, “you do need to follow general hypertrophy training principles (i.e. general sets, reps, rest intervals and tempos) in order to ensure that you continually create the optimal stimulus for muscle growth.”
Find a strength coach or personal trainer that has helped people in a similar situation to you and follow and stick to their system.
