1. Cardiovascular Endurance
Let me be more specific:
I recommend 20-60 minute of cardiovascular work most days of the week. Get that heart pumping and perhaps try to sneak in that 60 minute cardio session once a week...the rest of the sessions can be shorter.
Strength train for at least 30 minutes 2-3 times per week with one day of rest between sessions.
Stretch out every single day.
Now, how much time do you spend on each of the components of fitness per week? Are you lacking in any one area? Are you right on track?
Maybe you run all the time, but don't do enough stretching. It's time to change all that. Try to focus on the components you're weakest in this week.
Let me know how it goes!
