It's time to shake off those extra pounds and get in shape, but with so many weight loss products on the market it can seem impossible to pick a strategy! To help you out, Rachael challenges a group of veterans from The Biggest Loser to test out infomercial weight loss products in our latest "Human Lab!"

Erik, Season 3: This Biggest Loser winner dropped 214 pounds on the reality show and maintained the weight loss for a year and a half ... before the pounds started creeping back. He is getting back in shape, but says he could use help with one area of his body. "I wouldn't mind being ripped," Erik says. "Every guy - even if they don't want to admit it - they're concerned about their biceps!" He is testing the Bodyblade, a tool that claims to improve core strength by providing a complete workout in just minutes a day.

Amanda, Season 8: "I lost 87 pounds on the show. But then I got back to my real life and working out 6- to 8-hours a day isn't possible anymore," she says, noting she has since gained back 20 pounds. "My biggest problem area is my lower half - my legs, my hips my butt - if I had something that was accessible to me that I could actually use and help me lose weight fast, I'd love it!" She is testing 3 Minute Legs, a lower body sculpting machine.

Sunshine, Season 9: She shed 114 pounds on the reality show, but is not satisfied. "I really want to get down to 10 or 15 pounds lighter than that," she says. "That would just be amazing!" Sunshine is testing the Hawaii Chair, which claims to give you a great workout while you sit.
