Workout first thing, so that it is done and the day can’t give you the excuse you need to opt out.
Drink some preworkout to give you the energy level you need to get going.
As far as effort, take it at your own pace. Check out YouTube tutorials to get some ideas for workouts. Be good to yourself and just know that it’s a marathon and not a sprint. Don’t go for 50 pounds, start with 20 and see how it feels.
Never ever be afraid to ask those that are serious about health/exercise for help. 90% of those are over the moon excited to help those that are truly interested. Don’t forget about your community around you and accountability partners!
Main thing – don’t give up. This is for you, and you’re worth it!
