Sorry if this isn't projected as clearly as it is in my head. Basically my program revolves around heavy compound weights days and sprint days, aiming for a controlled 'bulk' while maintaining speed and conditioning for sports.
We're all pretty self-aware of how our bodies feel, in terms of muscle size, fullness, definition etc. I don't know if it's something that I'm imagining or not, but I feel like the mornings after sprint training my muscles feel smaller and less hard. Then the mornings after weights days they feel hard, larger and full again. Is it right to be concnered that the sprint days, although short (30 mins), might actually be un-doing all the progress I make on the weights days? Is it even possible for this noticeable, cyclic muscle disparity to occur?
If it's helpful, my weights are continually rising on the weights sessions, so I don't think I can physically be losing muscle, but none the less I'm a little confused.
