I agree with the previous commenters to get your BF% checked. If the
goal is
fat loss, it's best to actually measure
fat loss and not
weight loss.
The
gym should have a hand held
body-
fat monitor laying around. If they want to charge you for the test, walk away. You can buy your own Omron
Fat Loss Monitor for $20-$25 on ebay.
As well, the suggestion of
HIIT training is a great idea.
Cardio is best at improving your aerobic system, not melting
fat HIIT training is best at developing your
anaerobic energy system and is better than
cardio in melting
fat
Resistance training is best at toning various properties of muscular performance - strength, power, endurance,etc.. It can be effective for
weight loss if performed in a circuit training method
And finally,
diet is still going to be your most effective tool. It's much easier to eat 500
calories than to exercise away 500
calories. Sad but true
Hope this helps
