I feel healthier and empowered from doing BBG. The program helps me stay accountable because I want to check off all of the required workouts each week. (I use the app and the quote at the start of the workout, and the confetti and trophy it shows at the end of the workout is surprisingly motivational.)
I feel more toned and can definitely do more pushups, burpees, and commandos than I could at the start of BBG. But my biggest qualm about BBG is that all of the transformation pictures can be disappointing if you don't finish the 12-weeks with abs and a drastic transformation.
Although I feel stronger and more toned, my progress photos from the start of BBG to the finish aren't substantially different. But I try to remind myself that everyone is different and that the major transformation might not happen for me in the first 12-weeks. Also, I feel less stressed and happier when I workout regularly which is beneficial on it's own.
I recommend Bikini Body Guide. The 28-minute workouts and short HIIT sessions are quick and convenient and you can do them from home. The workout program can fit into your busy lifestyle better than an hour-long class, and it helped me stay accountable. Everyone's fitness level and experience is different, but it has been beneficial for me.
After finishing all 12 weeks of BBG, I can confidently say that it works. You'll be sweaty, and you'll savor the minute-long break between sets, but at least your hard work will pay off.
