I’ve been training consistently for about 4 years, but this challenge really gave me new insights and helped me push my limits again. Even with a full-time job, it was super easy to fit into my routine and kept me motivated. The workouts are clear, effective, and definitely make you step out of your comfort zone (and trust me, you feel it ). I’ve noticed progress not just in strength, but also physically, my shape is more toned and defined than ever! Honestly, this challenge is a must if you’re looking for that extra boost to level up 🙌💖🤝
