There are two methods for training with BrainHQ without having to purchase a subscription.
The first is available on our homepage at www.BrainHQ.com. Scroll down to the section called "Try a few exercises" to find four exercises you can train with for free.
Next is the Daily Spark. The Daily Spark is a feature built into the Personalized Trainer that will allow registered users to train with one new level twice a day. (Tip!: The exercise levels that are selected for the Daily Spark are on a rotation, so if you miss one day of training it will be available again a few weeks later.)
For more information about how to access the Daily Spark, please refer to this article.
