This is what I learned for myself. I don’t not always train to failure. About 80% I do go to failure. If you have been doing HIT for a long time you do not have to always train to failure.
I will try to keep this on topic and what changes I have made and why.
With 30/10/30 if I cant get to the last negative I dont worry about it. I would just stay with that exercise until I could.
I may do whole workouts that I don’t go to failure. Or I might only go to failure on some exercises and failure to others in a given workout.
I was doing 30/10/30 for a while but I had to make some adjustments. I based it on my a few things I have learned about myself over the past 30 years.
Like I mentioned I don’t stress if I fail before I can get to the last negative. Just keep the weight the same till I can. So sometimes I went to failure and other times I did not.
But thats one reason I don’t use it all the time on every exercise.
I found I like 30/30/30 on some exercises. Something with a shorter range of motion two reps with 15/15/15. Or even a few reps at 10/10. Yes superslow.
As you can tell by my name I like dips. For a while I was doing one 45 second negative like Dr.Darden wrote about. 45 seconds works better that 60 seconds for me.
I now like one 15/15/15 rep on dips I can focus better. With added weight I found I use better form.
I train alone. There are a few exercises that I only do once in a while for a change. Leg curl,extension, and lateral raise.
If I want to use 30/30/30 or 30/10/30 on those and I can’t get the weight in position for the first negative one or two reps at 10/10 first does the trick.
Sometimes I like one 30 second negative a few reps at 10/10 to a 30 second negative.
Sounds complicated but it really is not for me. I plan my workouts. I might do the same routine for 3 cycles. Then change things up for a few cycles.
I have arthritis and a few other health issues. For me it’s about training for health and staying
in shape.
I don’t lift as heavy as I use too. I would rather not have the aches and pains that I get from real heavy weight and moving at about 2/2 0r 3/3. You get the idea
With what I do now I can still go fairly heavy and make exercise harder by slowing down. I never got anything form a static hold ect so it’s a waist of time for me.
I have found a few moves I like and can do well. I stick with those and work them hard. I could go on about which exercises I like and those I do not.
What works for me may not work for another I said enough already.
