Jacks Into Push Ups

You'll start standing with jumping jacks to get your blood moving and warm up your shoulders, then drop down for push-ups that demand more from your upper body. The transition from vertical to horizontal keeps things interesting and hits your muscles from different angles.

This is a textbook exercise snack – brief, vigorous, and effective. Studies show these short bursts of activity can improve cardiovascular fitness and boost mental clarity, making it a practical option when you need to shake off brain fog.
