Can you acheive that body tone? Yes. Will it be easy to acheive? I have no idea.
How easy or difficult will be will depend on a a variety different things. Here are a few of them.
Where are you at right now?
What is your metabolism like? Some people have a very fast metabolism and are able to stay slim no matter what they eat. Others, not so much.
What does your current diet look like?
How much exercise do you currently do?
I applaud you for taking the step to add aerobic conditioning into your life. Remember to start slow. Lots of people are super motivated on day one, over do it, and then take a week or more off while the soreness goes away.
Be prepared for gradual increases in fitness and body composition. Good luck to you!
