1.Find a good training partner.
2.Only do compound movements(squats, bench, deadlift, pullups, pushups, dips, ect..)
3.Focus on developing good form before bumping up the intensity.
4.Diet predicts your results, can train all you want but a ****tty diet will put you two steps back.
Example program:
Mon-chest: 5 sets of 10 for all chosen movements.
Tues-legs: 5 sets of 10....u get the idea.
Good luck!
