Does your gym offer free classes?
If so... Here is what I would do to get supper fast results...
1. Take a spin class regularly...
Reason... Its supper intense, but you can take at your own pace... You should sweat up a storm in that class... And burn a gazilion calories! (well... a lot of cals at least... )
2. Take a yoga class...
Reason... Your body is probably all stiff and needs some good
core strength and increase in flexibility to prevent injuries and help with any minor aches and pains you currently have...
3. Take a palates class...
Reason... It will tighten your core and stomach up so fast you will see a sexy mid section before you realize it... Plus, a stronger core equals a stronger body for lifting the weights... It makes a huge difference to your weight lifting!
4. Take a total body sculpting class
Reasons... Not all gyms offer this, but if they do, it is a perfect place to learn the different full body exercises that you can also do on your own in the gym itself...
To sum it all up... The reason why I think you should do those classes first...
Your body is your body... You need some time to get accustom to what your body can do in a athletic setting... The more comfortable you get with your body, the better you will be able to exercise and reach your fitness goals...
Also... a hidden benefit that you get with the classes that you won't get with just hitting the flow on your own is the new friendships you will build...
The men and woman with the most success have someone they can count on in the gym to help them through the workouts... i.e. Work Out Buddy! :-)
And by taking 4 classes for a few months at minimum, you will have plenty of time to make new friends and possibly find yourself a workout partner...
This workout partner will rely on you to get to the gym when you say you will... And that will FORCE you to go!
What is the biggest failure why people don't succeed in their fitness goals?
Because they fail to even show up...
