What really makes you bigger is not enough activity and eating too much!  Maybe you have started taking classes and/or working out on the cardio machines and you notice your clothes are fitting differently, even though you haven’t increased caloric intake or weight training.  Most likely, the reason is you are working new muscle groups, building new muscle and losing body fat.   During Spinning class, climbs don’t usually last for more that a few minutes – not enough time towards bigger legs or a bigger butt.

What makes you leaner is creating a calorie deficit through a healthy diet, regular exercise and strength training – so get out there and move…by the way – a 40 minute Spinning class burns an average of 400 – 500 calories – a great place to start.
