I love the gym, love the feeling after a great session, I, however am wondering how I am to make it through the week with all this cardio??? 🙈 today with the sun shining it was hard, I felt like i was in the desert! However, i know my cardio needs major improvement! So heres hoping and praying to all the gods in the world i make it through it! 😂 If anyone has any tips for during HIIT workouts please feel free to share them with me 😇 thanks!
