Britany Williams on Instagram: "Day 5 of my 12 Days of Christmas workout 🥳🎁🎄 HOW IT WORKS ➡️ Each day, for 12 days, I will share a new bodyweight exercise here on IG. Each day you’ll do all of the previous days’ exercise and add on that day’s exercise. So on Day 1 you’ll do just one exercise, on Day 3 you’ll do all exercises from Day 1-3, on Day 9 you’ll do exercises 1-9 etc. Day 1 - Squat to Knee Drive (8 reps p/s) Day 2 - Lunch to Punch (8 reps p/s) Day 3- Crescent Lunge Knee Drive (8 p/s)
