Use supersets in your strength training.
Rather than doing all of one exercise and resting before doing the next set, go immediately from one exercise to another.
For example, you could do eight reps of bench press then 10 chest flies. After a 90-second rest, repeat. Do this for three to four rounds.
This also works great with full-body workouts, pairing an upper-body move with a lower-body move.
