Here is a varied workout with 3 different parts that mainly focus on your legs and glutes, but with a bit of upper body too. You need a circle band, a high step, and preferably some dumbbells and / or a kettlebell.
Circuit 1 (repeat 3 times):
15 banded squats
10 side step ups (each side)
20 walking lunges
Circuit 2 (repeat 3 times):
10 lateral lunges with press up (each side)
20 alternating lateral lunges with jump in the middle!
Dumbbell or kettlebell swing build up!
Start with 14 reps in a minute, then each minute add 2 more reps for a total of 30 reps.
Focus on technique and don't get sloppy with your form!
