If you're tired of painstakingly doing the same workout each day, I highly recommend trying out JSF.
I wasn't out of shape before joining JSF. I worked out 3 days a week (4 on a good one) or so where I went to mountainside and did the same circuit over and over. My workouts were became boring and I spent more time trying to find new ones than I did actually working out.
Joining JSF gave me a consistent schedule I could hold myself accountable for. All you have to do is show up and you are done with a hard workout in 30 minutes.
The workouts are a great balance of cardio and lifting to ensure a full body workout. It's also not a crazy CrossFit Olympic workout that requires technical expertise to avoid injury.
Whether you are looking to get started, or want to get out of a rut of workout you've been doing since college, check out JSF.
