Squats just squeeze it in when u have time. I got days like that to. Not everyone has all the time in the world!
I also have a range of 5-10min workouts that I made and alot of booty ones check it out if you like :)
Hope you find one that can help! I do one of these everyday and definitely notice a difference each week. <3 Tricky
Do squats while you brush your teeth. That way you save your 10 minutes a day for somew else.
Personally I get more of a butt workout with lunges than I do squats. If you can lay on the floor, do pelvic thrusts. They may look odd but they target the glutes like crazy. Try doing them slow all the way up and down. Then switch to half way going down and up, after a while half way to all the way up then back to half way. To intensify lift one of your legs up. Also, if you do decide yo do squats, do sumo squats. They target the glutes better than the traditional squat.
