Healthy does HIIT: outdoor workout
Doing some dynamic stretching for 3-4 minutes will raise your heart rate and increase mobility and flexibility in the joints. Try raising your knees, twisting your upper body from side to side, plus some squats and static lunges.
Outdoor HIIT session
Find a friend and hit your local park for a winter workout. Do each exercise for 45 seconds, then rest for 15 second intervals. Repeat 5 times – a full circuit should take 5 minutes, but repeat if you have more time or want to increase the intensity.
Run or a brisk walk.
Tricep dips on a park bench. Try to do as many as possible without losing good form.
Plank position. Ground too cold or wet? Try press-ups against the back of a bench instead.
Step-ups on a bench.
Start with a slow walk for 1 minute while stretching out your upper back, triceps, and chest to allow your muscles to cool down after the HIIT work-out. Then do some standing stretches for your hamstrings, quads and hip flexors for 2-3 minutes.
