The Fourth of July sale has finally arrived. There are plenty of home gyms out there to help you stay fit, but few are as smart as the Tempo Studio. This smart home gym can help you with everything from strength training to cardio. Plus, it's on sale right now.

For a limited time, the Tempo-Studio is on sale for $2,095 with coupon "Tempo-4th". That's a $400 discount and the lowest price we could find for this workout mirror. Incidentally, Best Buy has it for $2,599.

For those of you who don't know Tempo Studio, here's how it works: Tempo Studio is basically a 42-inch smart display that uses infrared pulses to create a 3D model of you during your workout. It then makes suggestions to perfect your form and improve your overall strength capacity; the AI is smart enough to suggest recommended weights and count reps. It's like having a digital personal assistant every time you train at home.

For $39/month, you also get access to live and on-demand classes. (12-month commitment required). Classes range from strength training, HIIT, mobility, cardio, and recovery classes.

The Tempo Studio includes two 42-inch touch screens, two 7.5-pound dumbbells, one 25-pound barbell, six collars, four 10-pound plates, four 5-pound plates, four 2.5-pound plates, four 1.25-pound plates, heart rate monitor, workout mat, and recovery roller included.
