No problem. Remember work output/volume is an individual thing. I burn out quickly, it's how I'm made. I often need a touch more recovery between heavy sets....it's ok though, it's an individual thing. There's no way I can match some of the rep outputs some here have achieved but I can improve upon what I've done!
You burned out at 24 minutes.....may I humbly suggest the 20/25/30/25 session length template?
Week one being 20 minute sessions, week two 25 minute sessions,etc. I've found using a good solid pace each workout for the first three weeks and turning up the density in week 4 is effective. In my mind it's less daunting. I burned out a bit keeping thirty minute sessions for the first three weeks...in my mind I kept pushing too much each workout. This way I find that the volume naturally increases, even if it's just slightly each week because of the increase in time per workout per week. Then turn up week 4s density.
