Here's a melodic I-IV-V-I workout designed to loosen your fingers and stretch your ears. Some highlights:

Bar 1 features sweep picking through an ascending and descending A13 arpeggio. Follow the picking indications carefully.

Bar 2 offers country-fried double-stops based on the major pentatonic scale, served with a side of chromatic passing tones. Use alternate picking on this D7 passage, and notice how -- thanks to the triplets -- only beats one and three start with downstrokes.

Get out the broom again in bar 3. As in bar 1, pay close attention to the downstrokes, upstrokes, hammers, and pulls. Play them right, and the Eaug arpeggio will unfold smoothly.

Wrap this line up loud and proud with a bluesy, arpeggio-based A7 lick. That last whole-step bend is fast, so use three fingers for strength.

Hide the seams. Practice this phrase slowly and deliberately with a metronome. The trick is to avoid sounding as if you're "punching in" chord by chord. Let each melody flow into the next.
