Hey Big Man, I hope you and your family are well.
This is the time to bring out that training methodology I call The Power of Less. It's a time to take advantage of what I also call SR, that stands for Summit Reps. Basically, once you've reached the mountain top (the summit), you want to stay there for an extended period of time in order to fully take in and be elated by the incredible view you're able to see from such a magnificent height.
I won't bore you with intricate details here, suffice to say the following: look at what you've been doing before, and begin the SR by doing less for more. I'll give you an example to illustrate my point.
Say you've been doing biceps curls for 5 sets of 10 reps, resting 60 to 120 seconds between sets. If I was to break those reps down into effective and activation reps, I would end up with about 30% effective and 70% activation. Your aim now (performing the SR method) would be to curtail / minimise on the activation and throw all your focus onto the effective reps instead. After all, once you're standing on the Summit, you would not want to climb back down the mountain, only to climb back up again. Once there, stay there.
So this: 5x10, becomes this: 10, 4, 3, 3, 2. With a rest of 15 seconds (instead of 60 to 120 seconds) between sets, you've not only saved yourself a tremendous amount of time, but you've also kept the essence of each and every set, whilst discarding the rest (those activation reps leading you to your effective SR).
So now grab yourself a piece of paper and begin to write down all that you were doing, and the time it took you to complete those exercises. For the SR, I'd only pick one exercise per body part and do that before moving on to the next exercise. I'll leave it here for now and welcome any question/s you may have for me. All the best Mick.
