We've all probably wished for a way to achieve our fitness goals without the strain and sweat that can come with exercise.So what if you could lose weight, gain muscle and improve circulation just by standing on a vibrating platform?Norman and Tegan buzz through the evidence for and against vibration plates and so called "passive exercise".References:Dr Gustav Zander’s Victorian-Era Exercise Machines Made the Bowflex Look Like Child’s PlayThe effects of whole body vibration therapy on reducing fat mass in the adult general population: A systematic review and meta-analyses Whole-body vibration administered during a 3-week in-hospital multidisciplinary body weight reduction program increases resting energy expenditure in obese adolescents, a randomized clinical trial Immediate effects of localized vibration on flexibility: A randomized crossover trial Effects of whole body vibration with exercise therapy versus exercise therapy alone on flexibility, vertical jump height, agility and pain in athletes with patellofemoral pain: a randomized clinical trial Whole Body Vibration as an Adjunct to Static StretchingWhole-Body Vibration Stimulates Microvascular Blood Flow in Skeletal Muscle Whole body vibration training improves leg blood flow and adiposity in patients with type 2 diabetes mellitus Effects of Whole-Body Vibration Training on Lower Limb Blood Flow in Children with Myelomeningocele—A Randomized Trial Effect of localised vibration on muscle strength in healthy adults: a systematic review Whole-body vibration training improves muscle mass and strength in older adults through intra- and extra-muscular pathways The effect of whole body vibration training on quadriceps voluntary activation level of people with age-related muscle loss (sarcopenia): a randomized pilot study Hormonal responses to a single session of wholebody vibration exercise in older individualsHormonal and Metabolic Responses to Whole Body Vibration in Healthy Adults Low-frequency vibrotherapy considerably improves the effectiveness of manual lymphatic drainage (MLD) in patients with lipedema: A two-armed, randomized, controlled pragmatic trial Efficacy of whole body vibration exercise in older people: a systematic review If you enjoyed this episode, check these out!Can you zap yourself buff with electrical muscle stimulation?Do the benefits of creatine go beyond the gym?Do healthy people need lymphatic treatments?

Snail slime, or snail mucin, has become a popular product in skin care.Some claim it has anti-ageing properties, but if the early research shakes out, snail mucus could have even more significant uses.Norman and Tegan discuss why snail gunk has become a hero of cosmetics, and what else it might be capable of.References:Why Snail Mucin?

Walking down the street, most people you pass will be wearing headphones or ear buds.
