If you dont belomg to a gym, or have access to weights, maybevyou should use bodyweight exercises.
If you DO have access, the basics are the same:
Larger muscles first. LEGS /BACK/ CHEST/SHOULDERS/ BICEPS/TRICEPS/ABS.
Although you run, deep SQUATS, bodyweight or with a barbell, stimulates your ENDOCRINE SYSTEM, releasing HORMONES that cause muscle growth in your ENTIRE body.
At first, until you get a feel for it, stick to basic exercises for each bodypart you are training.
BODYWEIGHT: Squats, Chinups, Pushups,,& situps or "crunches
IRON:Squats, Bent over Row (barbell or dumbell), Standing Military Press, Standing (barbell or dumbell) Curls, Dips,and weighted crunches (either with a cable machine or with weight plates on your chest.
Once you begin to bench press your body weight, you will really start to grow.
Until then, practice the movements of the exercises with little, or no weight until you get the groove of it.
Then, go for 3-4 DIFFERENT exercises for each bodypart
10 - 12 repetitions for 3 - 4 SETS
And , do this CONSISTENTLY 4-5 times a week, increasing the weight as you feel stronger, for 3-4 months. You may want to divide the bodyparts you are training into different days .
And this is a good beginner routine.
For bodyweight exercise routine, try for 40 repetitions of each move, divided into segments if you have to, until you can perform them ALL in a smooth, uninterrupted routine, and do this EVERY morning before you leave the house
