dot said:oh, you keep telling me. I like my trainer, I truly do. But I can't keep going hard for long periods of time. It really kills my mind. Killer accelerations or hard 3x3x30x30 sets, anything short and painful - they're fine but anything longer 4-5 minutes, I start to hate everything around, kinda demotivating.
Instead of thinking about the effort that you're currently doing, think about why you're doing the training in the first place. Focus on your goal.
If you have no goal, in all likelyhood, you'll probably not go hard enough to complete the training properly.
It could be that you're going too hard and it's just not possible to keep the effort going but if that's not the case and your goals aren't enough to motivate you to complete the training properly then maybe you need to rethink more than just your current training woes. Maybe the time allocated to your next trainer session should be spent re-thinking and planning...
