Build Full-Body Strength in Just 25 Minutes with Equipment-Free HIIT

Personal trainer Rhiannon Bailey has created a 25-minute HIIT workout that requires no equipment and can be done at home or outdoors. The routine includes jumping exercises for leg strength and core-strengthening exercises like plank jacks. Each exercise is performed for 40 seconds with 20 seconds of rest, and beginners can modify the intervals. Maintaining proper form and engaging the core muscles is important. Expect some muscle soreness the next day, but rest and adequate protein intake will aid in muscle repair and growth.
