American superstar Jessica Simpson has enlisted the help of a personal trainer to help her slim down for her wedding.

To get her in shape for her wedding Jessica’s trainer Tracy Anderson has costimised a fitness routine that involves aerobics, dance, strength training and ab work.

Jessica’s fitness training will be made up from 75-minute, four-day-a-week workoutsJessica’s workouts are designed to help her toned up, as the singer and fashion mogul insists that she interested in being rail thin she ‘just wants to look healthy’.

The singer started her new fitness regime a few weeks ago and 'She's seeing results,' says an insider. 'She really loves it. She thinks it's so much fun.'

After struggling with her weight over the course of the past few years, it seems that singer Janet Jackson has piled on the pounds once again. The singer who weighed in at a slender 120lbs just a few months ago, has gained 20lbs over Christmas and is desperate to lose weight for her comeback tour.

Like many of us “Janet lost control of her diet at the end of last year, then she went hog-wild on junk food over the holidays,” a source told American tabloid the National Enquirer.

But it seems Janet has been trying to get back into shape with a extensive exercise routine. She’s working out seven days a week, swimming, doing aerobics, kickboxing, running and lifting weights.

And she’s hoping that the nightly workout of performing onstage will help with her weight loss, too.

Her new tour is a ‘greatest hits’ show – and Janet is determined to make it her best tour ever, whilst looking her best whilst doing so.

A combination of aerobics and weight training has been found to be the best exercise regime for Diabetics.

The combination of aerobics and weight training helps to lower blood sugar. Blood sugar is burned faster during aerobic activity as blood sugar fuels the muscles. Weight training builds muscle and changes muscle protein as with aerobic training, this enhances the bloody sugar burning process.

The study also highlighted that mixing aerobics and weight training is also one of the best ways to lose weight, when compared to using the exercise regimes as individual regimes rather then together.

The patients who took part in the study exercised three days a week for 45mins over a period of nine months.

The study used three exercise routines that could be recommended to diabetic patients by doctors. One group of patients were given aerobic training as their exercise regime, the second group were given weight training as their exercise regime and the final group combined both methods of training.

Researchers found that the group who combined aerobics and weight training were the only group who lost weight and lowered their blood sugar.

As a result fewer patients in the combined group started taking new diabetes drugs than the patients in the other two groups. Decisions about the patients medication was left up to the patients’ GP’s to decide.
