I tried the Tone It Up Bikini Kettlebell Workout yesterday and I walk like an old grandma. :D It´s almost 20 minutes long, contains a short warm up and cool down and 13 exercises. Some of them are really intense. The Kettlebell Swing is really long and I felt like wanting to stop several times. The Burpee Press is a new variation of a Burpee and I really liked it. Also the Side Plank Swing was kinda tricky but you definitely can see a progress after you have done this workout several times. This workout is also doable with dumbbells. I had a 3kg dumbbell instead of a kettlebell and it worked out fine.
Have fun with it! :)
