I used the Sweat workout app for two weeks to build and maintain strength without the gym. Here are my four major takeaways

I've been a regular gym-goer for three years now, two of which have been spent at a CrossFit box, with a focus on weight-training. When it comes to building strength and improving my fitness, I know that lifting weights is what gets me results.

However, I regularly travel, and sometimes when I'm away or busy with work I don't make it to the gym as often as I'd like. As a result, I'm trying to incorporate more home workouts into my routine. In lieu of a coach and guided workouts at the gym, I decided to try the workout app Sweat created by the personal trainer Kayla Itsines, who also posts workouts online to more than 16 million Instagram followers.
