Trends: Call now to lose lbs, lbs, lbs!

Anyone looking to slim down for the beach this summer could do worse than getting on their mobile. No, nattering away won't shed the pounds, but a new generation of phones that double as virtual personal trainers should help.

Samsung recently tied up with Adidas to offer miCoach ( www.micoach.com), which uses sensors in footwear and clothing to monitor your vital stats and delivers tailored workouts to your phone.

Nokia's prototype Eco-Sensor (www. nokia.com/ A4707477), meanwhile, will monitor everything from humidity to vehicle pollution levels.

And HealthClubTV.com, launching later this month, will offer minute-long exercise videos that can be downloaded direct to mobiles. Now we just need a phone that can deliver willpower.
