Circuit 2, Exercise 1: Forward Backward Lunge

  • Stand with the feet together.
  • Put weight in the left foot, lift your right knee up, and step into a forward lunge. The front knee should be at a 90-degree angle with the left knee just barely hovering above the ground.
  • Push into your right heel, come to stand, and immediately step the right foot behind you into a reverse lunge with the left knee at a 90-degree angle.
  • This counts as one rep.
  • Complete 15 reps on each leg.

When's the last time you did a workout that took less than 30 minutes and left you feeling strong and in a better mood than when you started? If you can't remember, we recommend bookmarking this page, because this 20-minute bodyweight workout from Brittany Watts, a NASM-certified and Performix House trainer will do just that.

Not to mention, it can help you develop lean muscle in your lower body, especially in the glutes (but you're going to have to be consistent with training and your nutrition for those results!). "Efficient and effective, this workout is perfect if you don't have a lot of time," Watts told POPSUGAR.

Brittany Watts's 20-Minute Bodyweight Abs and Lower-Body Workout

Directions: Before getting started, Watts said to do a dynamic warmup, incorporating exercises like plank walkouts, leg swings, and jumping jacks - here's one we really like.

This workout is broken up into three circuits. You'll complete all three exercises in each circuit for the designated reps/time, taking little to no rest in between each exercise. Once you've finished all three exercises, take 30 seconds of rest, repeat the circuit two more times for a total of three rounds, and then advance to the following circuit.

Don't forget to cool down and stretch and maybe even foam roll once the workout is over.

Circuit 1

  • Circuit 1, exercise 1: high knees: 30 seconds

  • Circuit 1, exercise 2: squat jump: 20 reps

  • Circuit 1, exercise 3: reverse lunge to curtsy lunge: 15 reps (each leg)

Rest for 30 seconds and then repeat for a total of three rounds.

  • Circuit 2, exercise 2: lateral lunge with knee drive: 15 reps (each leg)
