You can do stronger lifts once a week if your workout includes high-intensity, high-volume protocols that focus on compound exercises for the whole body.

When it comes to strength training, doing something is better than doing nothing. The recommended frequency is 3 days a week for good profits. You don't need to spend hours in the gym to see the results.
