Summer puts the pressure on our workouts, big time. But spending hours at the gym is something we just don’t have time for. Not to mention, working too hard just results in dreading your next workout.

The fabulous trainers Karena and Katrina over at Tone It Up just released a 30-minute workout video that features powerful combination moves (think: working more than one muscle group at once) that are guaranteed to get your heart pumping.

One look at their physiques, and you won’t question it. This video is free (love that!) and so helpful for anyone who travels or just doesn’t have time to leave home to workout.

Watch it below, and let us know what you think!
