Week 4 Day 4 //Total Body HIIT CARDIO + ABS // Power + Strength Workout – Heather Robertson

Today’s total body HIIT is full of some killer moves to help improve strength and power. We will also target the core and work on that six pack with a quick ab finisher circuit. It’s going to be good and sweaty my friends. Let’s do it!

Breakdown: Full body HIIT circuit x2 rounds 40s work + 20s rest
Abs workout x2 rounds 20s work + 10s rest (take 0s rest for an extra challenge!)
Equipment Needed: dumbbells + exercise mat or other soft surface.

*Dumbbells are always optional. You can add them or remove them from any exercise. You do you! 🙂 Choose a weight that is challenging but allows you to perform each movement with control and correct form. This weight will be different for each individual! Ball size should be chosen based off of your height. I highly recommend using the ball as it provides additional core and stability work but you can always use a bench, ottoman or perform many of the same exercises on the floor.

So that's almost the end of the first month. I have to admit that apart from week 1, which was an absolute killer for me, this fourth week's been the worst. I'm tired, still unable to do the pumps properly and my weight hasn't changed even 1kg. I've been very careful with my diet. I have to say I am a bit frustrated… I feel well though, but that's all…

I didn't take a break with the HIIT part today because I took few in yesterday's workout. I finally got to experience that exercise-induced endorphin rush that everyone talks about. Totally worth it. Thanks a lot Heather❤️ The scales and inches may not have budged yet. But the improvement in stamina and general moods is so apparent everyday

Missed a day earlier this week so doubled up today on day 3 and 4. Insane combination the two most difficult workouts in the program yet. Proud of myself for banging them both out with minimal modifications though. Will definitely be archiving this one whenever I need a quick, effective cardio circuit. Week 4 day 5 tomorrow! Cannot believe it has been a month already!

I don't know which is the magic behind this program… It's the first time in so much time (probably years) that I do exercise 5 or even 6 days per week!
Thank you so much, Heather!

Week 4 Day 4!! Almost gonna complete 4 weeks!! Today's workout was really intense! Also, I skipped jumping in some and did them with dumbbells rather! I know that is not very okay, but I am working on it!

I had stopped the workout for a few days due to local vaccine pain, then came back today full of energy. Almost stopped a number of times. It was very hard to follow it today, and I had to make some adaptations, but w4d4 is done. And will be back tomorrow.

I had to modify the lunge jumps on the second round to just reverse lunges because I thought I was going to die!

Fatigue has hit me bad today but somehow I got it done ✅ Still can't get my legs high enough for those tucks but I'm ok with that, I care about my knees more 😂🤪 I did pop lunges instead of jump lunges which is basically the same thing in a way 😉 only 1 more day left & Week 4 will be done!

Am I the only one who felt that today's workout was easier than ere yesterday's workout? My maximum heart rate recorded during this session was 155 bpm. I think it is because of Heather that I am able to workout with full intensity without my heart rate going above 180 bpm. Thank you Heather, I am seeing visible change in my heart rate readings. You are amazing!
