I have a child and I thought like you are right now, but let me tell you that a child is a blessing and missing a couple workouts here and there is well worth it when he/she grows up and is looking at you as a father and a role model and wants to spend time with you and not just his/her friends. Keep in mind all the shit heads out there that don't take care of there children and look how they turn out just like the father SHITHEADS. Be strong and most of all be a father to this child and believe me you will find the time to train. Congrats on the child!! and good luck.
Your world is going to change big time, but let me tell you it is going to change for the better!! I have four kids 3 girls and 1 boy. You will just have to manage your time and make time to keep working out, it can be done. The fun part is just now starting for me. My oldest girl just turned 12 and her little boy friends get all freaked out when they see me they know whats up!! and what will happen if they touch her LOL the joys of being a daddy.
