Sharon's Fitness Training Personal training is just that - personal. I adjust each session to help you achieve your goals based on how you’re feeling that day. Sore lower back?

Let’s work around it. Sleep deprived? Let’s keep it simple
Wedding in a month? Hard work incoming I have been working in the fitness industry for the past 6 years. I started out as a Group Fitness Instructor for Body Pump, then slowly added more qualifications including Gym Instructor and Personal Trainer. In 2011 I discovered CrossFit and have since competed at the Australian Regionals twice a

team member of the Crossfit Adelaide team. I have also placed as an individual in the South Australian FitWars competition both as an individual and as a team member. I was the first qualified CrossFit Level 1 trainer in the Mount Barker area. My training style varies depending on what clients are after. However I believe strongly in the CrossFit ethos of constantly varied, high intensity, functional movements. You won't find me using too many machines to get you reaching your goals - instead I use Olympic bars and bumpers and kettlebells and slam balls, a rower, skipping ropes, pull up bars, tyres, an aerodyne, gymnastic rings, sleds that can be pulled or pushed and of course your own bodyweight is the best machine! I prefer to train in half hour sessions as I find clients respond best to the short and sharp sessions. It's also easier to fit a half hour session into your day! I do encourage clients to arrive 5 minutes early and warm up and cool down on your own so I can make full use of the half hour. Why get personal training? A generic gym is cheaper for sure - but you're not accountable to anyone. No one knows if you miss a session, or two, or three, or if you aren't coming at all. It's a high possibility that you're not pushing yourself enough either. When you are finished a session you should be, well, ummmm, exhausted! Having to be accountable to someone, having to sit on the bike and answer my questions "so how's your nutrition been?", "what exercise have you been doing on your own?" etc makes you accountable. You won't waste time doing any exercises that you don't need to. Everything we do has a purpose. It's my job to keep up to date on the latest health and nutrition information and to pass that information on to you.

The "fat-burning zone" is the setting people deliberately choose to lose fat, and it is the setting that burns the fewest calories. That is the whole problem with it.

At low intensity, the highest share of your fuel does come from fat. Romijn and colleagues tracked substrate use across intensities and showed that as you go from easy to hard, carbohydrate use climbs while the percentage of energy coming from fat falls. The machine label is not lying about that part. Easy effort genuinely burns the largest fraction of calories from fat.

A percentage is not an amount. Easy effort burns a high share of a small number of calories, and harder effort burns a lower share of a much larger number. A bigger slice of a smaller pie is still less pie. This is why two people can both be told they are "burning fat" and end up with completely different results depending on how much total work they did.

Peak fat oxidation does not even sit in the marketed zone. Achten and colleagues found that the actual maximum rate of fat burning, the point they call Fatmax, lands around 64 percent of VO2max, roughly 74 percent of maximum heart rate, which is a moderate effort that feels like work, not the gentle pace the "fat burn" setting points you toward. Fat oxidation then drops off sharply at high intensity. The zone is set too low even on its own terms.

The fuel you burn during a workout does not set how much fat you lose. Over the following 24 hours the body balances its books. Burn more carbohydrate during a hard session and you oxidize more fat at rest afterward, and the reverse holds for an easy one. What remains at the end of the day is the total energy deficit, and that is what fat loss actually tracks.

Choose training by the total energy you can put in and sustain, not by a zone named after a percentage. The most effective session is the one that builds the largest deficit you can recover from and repeat, whether that is a long easy effort or a short hard one. The label optimizes a ratio. Your body responds to the total.
