If jason wants to build muscle mass in a healthy way, what kind of exercise should he include in his fitness program?

The five-by-five program is one that is quite popular among those who are looking to gain a high amount of strength and muscle mass.

The set-up of this program is to perform three main exercises that target the main muscle groups in the body (both lower and upper body in the same workout), performing five sets of five repetitions. At the end of each workout you can add in a few sets of isolated exercises if you like, but it's not required by the program.

One of the biggest advantages of this set-up is going to be an increased frequency of training. Since you will stimulate so many muscle fibers every other day, you will see a very high release of testosterone, promoting a good degree of muscle mass growth.

Most individuals also find that they become hungrier while following this program, which is representative of the intense nature of it.

The drawback to this program is that it's one that a beginner likely shouldn't jump into as it will be intense and could lead to overtraining if you're not careful. It's best to have a 3-6 month lifting history behind you so you can be sure your body is ready for this stress load.

The second con to this set-up is due to the fact that you'll be lifting heavy three times a week - it doesn't lend so well for a lot of other activity, such as heavy sports training. If you're involved in high-level athletics, it may be better to choose a slightly less demanding program so you don't become overly fatigued.

You'll want to aim to perform the 5 X 5 protocol for the core exercises as described above and then cut back on the volume for the accessory lifts.

If you know going in you're someone who tends to have difficulty recovering, then you may want to attempt a 3 X 5 set-up first and see how you do. It can be easy to overtrain on this program if you're not careful.

Alternate between workout A and workout B three times a week with at least one day off between sessions. Aim to rest for 60-to-120 seconds between sets of the core exercises and 30-to-45 seconds between sets for the accessory exercises.
