The age-old question within the topic of fitness.
 
 What is your goal??
 
Usually when discussing this with clients or members of the gym, its weight loss or fat loss.
 

Well, if that is the goal. You need calorie deficit. Weight training and cardiovascular can help in many ways but are not the sole driver of weight/fat loss. Nutrition is.
 
If you want to improve your physical health, then which would be better, Cardio or Weights.
 
Again, what do you want to improve? Strength, movement, performance, general fitness??
 
Weights and cardio are two different things. Two tools that we use to improve physical aspects of our lives. What do you want to improve?
Some people are very anti-cardio or anti-weights. This usually comes from either being misinformed or just personal dislike.
 
A lot of people dislike cardio because they immediately think of 10km runs. Wrong. You can improve cardiovascular health by more activities than running, such as swimming, cycling, walking, or they think they will lose all their muscle gains. This can be true to a point. But, if performed and programmed properly, people can still maintain muscle mass while performing multiple cardio sessions a week. Again, it comes to how its done.
 
On the other hand, weights are generally avoided because people "don`t want to get too bulky"
Ask a body builder how hard it is to actually gain muscle. It is extremely hard and takes patience and discipline. Also, it requires consuming large amounts of calories daily. 
I am yet to come across someone in the gym that actually eats enough calories to fuel their daily activities, let alone enough to even elicit massive amounts of muscle growth to the point of looking bulky or manly.
 
So, which is better?
 
Let`s take a look at some of the benefits of both.
 
Benefits of Weight Training,
  ·      Improves bone density
  ·      Increases muscle mass
  ·      Increases strength of muscles, tendons, connective tissue
  ·      Improves quality of life.
  ·      Reduces joint pain and stiffness
  ·      Makes daily tasks easy to perform
  ·      Improves posture
 
Benefits Of Cardiovascular Exercise.
  ·      Improves lung capacity
  ·      Improves heart performance, strengthens the heart
  ·      Lowers blood pressure
  ·      Reduces risk of heart disease
  ·      Improves stamina and endurance
  ·      Lowers stress levels
  ·      Reduces joint pain and stiffness
 
Both weights training and cardiovascular training have their place. It is up to you, or more importantly, your trainer to decide what, when, how much you need to do to reach your goals.
 
There is no magical exercise, routine or modality. It comes down to what you can do consistently.
If there was the ultimate exercise that got you fit, string healthy and ripped, and you never did it, would you get fit, strong, healthy and ripped? No, you wouldn`t.
 
It`s what you do consistently.
 
If you want to get stronger, lift weights consistently.
If you want to improve cardiovascular health and performance, do cardiovascular training consistently.
If you want to lose weight, make better nutrition choices consistently.
If you want all of that, hire a trainer.
 
Having a trainer keeps you accountable. They have studied, they continue to study all aspects of improving physical health. They know how to push you, pull you back and keep you on track.
They keep you safe, keep you moving consistently and keep you healthy so you can stay on track and not get off track.
 
Be patient and keep consistent.
